Thomas Edison invented the light bulb in 1879 to illuminate the night. It has a filament, stem, and wires. Electrical energy can come from water, wind, or uranium and undergoes transformations from mechanical to kinetic to electrical energy power the light bulb. Inventors aimed to develop long-lasting light bulbs that didn't consume large amounts of energy.
Electricity
- Electricity was discovered near the Greek city of Magnesia in 600 BC. Benjamin Franklin later discovered electricity in the 18th century.
- One of the first electric machines invented was the light bulb, created by Thomas Edison in 1879. It used a filament to produce light and consisted of two vertical wires attached to the filament.
- The main parts of electric machines are generators, which produce electricity, motors, which use electricity to power mechanical devices, and transformers, which change the voltage of alternating current.
Project 12
Electricity was discovered in nature and studied experimentally in the 18th century by Benjamin Franklin and others. Thomas Edison developed the first practical incandescent light bulb in 1879 that could burn for over 700 hours powered by electricity generated from batteries. Before widespread electrical generation, power sources like petroleum, coal, and gas were used to produce energy to power light bulbs, but hydroelectric power from water and solar power have since been developed as well.
Electricity
While the ancient Greek philosopher Thales is often cited as the first to observe static electricity around 600 BC, electricity as a concept was not truly discovered until later experiments. One of the first electric machines invented was Thomas Edison's light bulb in 1879. The light bulb works by transforming various energy forms - mechanical energy from a generator is converted to kinetic energy and then electrical energy by transformers to power the filament and produce light.
Electricity
Electricity is a form of energy that results from the existence and flow of charged particles like electrons. It allows the transfer of energy through conductors like copper wires to power machines and devices. There are three main categories for generating electricity: fossil fuels like coal and natural gas; nuclear energy; and renewable sources like biomass, geothermal, and solar thermal. Benjamin Franklin proved that lightning was a form of electricity through his famous kite experiment in 1752. Over the next hundred years, inventors worked to develop practical uses for electricity until Thomas Edison produced the first reliable long-lasting light bulb in 1879.
History of electricity (3)
The Greeks discovered electricity in 600 BC by observing that rubbing fur and tree resin caused attraction. The first application of electricity was an electromagnet built in 1831 by Joseph Henry, which was used to lift heavy metals. Otto von Guericke invented the first electric machine in 1672, an electrostatic generator that produced sparks from a sulfur globe using energy from a piece of amber.
The light bulb
Sir Humphry Davy created the first light bulb in 1802, and Frederick de Moleyns received the first patent for an incandescent lamp in 1841. In 1875, Pavel Nikolayevich Yablochkov developed the first practical arc lamp, and in 1878 William E. Sawyer and Albon Man received a patent for a nitrogen-filled globe with a carbon conductor. While these inventors made early contributions, Thomas Edison is generally credited with inventing the first long-lasting, practical incandescent light bulb in the late 1870s.
History of Electricity
Ancient Greeks discovered static electricity in 500-400 BC. Benjamin Franklin conducted experiments with electricity in the 18th century and theorized its polar nature. Alessandro Volta then created the first battery in the early 19th century. This led to discoveries like the electromagnet and electric generator in the early 1800s. Thomas Edison developed the incandescent light bulb in the late 1800s and began powering homes with electricity. Nikola Tesla also developed the AC induction motor and left Edison's company to form his own using alternating current.

Generating Electricity
Electrons contain a negative charge and flow through wires, generating electricity. Atoms contain a nucleus with protons and neutrons at the center, surrounded by electrons. Scientists like Benjamin Franklin, Thomas Edison, and Nikola Tesla experimented with generating electricity in the 1600s. Electricity is generated today through wind turbines and steam turbines, which use kinetic energy to power generators that produce a flow of electrons.
Electricity history
The Greeks discovered that amber rubbed with fur could attract and repel light objects, demonstrating static electricity. Otto von Guerike produced sparks by rubbing sulfur, connecting small static sparks to lightning. Benjamin Franklin proved this connection by flying a kite in a thunderstorm. Later, Galvani accidentally discovered that electricity from a Leyden jar caused frog leg muscles to contract, believing the legs produced electricity. However, Volta showed the contractions were caused by the metals in contact with the frog's salty moisture, and he invented the first battery by stacking copper and zinc plates in salt water.

Photovoltaic (PV) cells convert sunlight into electricity by using layers of semiconductor material that release electrons when struck by photons. Edmund Bequerel first noted the photoelectric effect in 1839, and Albert Einstein later described its nature. In the 1960s, the space industry began using solar technology to power spacecraft. Solar panels work by sunlight creating direct current that is converted to alternating current and connected to existing electrical systems. While initial installation costs may be high and solar panels do not work at night, solar power has advantages in being renewable, reducing fossil fuel use, and stimulating economic growth in green jobs.
Electricity generation final presentation
Power stations located across South Africa generate electricity from various fuel sources like coal, nuclear, and hydropower. Coal power stations produce about 90% of South Africa's electricity by burning over 90 million tons of coal annually to heat water into steam. This high-temperature steam spins turbine wheels connected to generators that produce electricity. Alternative energy sources like wind, falling water, and sea waves can also be used to drive turbines and generators without relying on finite resources like coal.

Electricity
Michael Faraday invented the electric motor in 1821. He created a simple electromagnet using a nail, wire, and battery. He attached a spindle to the nail so that it could rotate when powered by the electromagnet. An electric motor uses magnetism to convert electrical energy into mechanical motion. It has six main parts: an armature or rotor, commutator, brushes, axle, field magnets, and a DC power supply. Common examples of electric motors include fans, washing machines, refrigerators, pool pumps, vacuum cleaners, and ovens.
History of electricity
The document traces the history of electricity from its earliest discoveries to modern AC power systems. It describes key developments such as: Benjamin Franklin's famous kite experiment which proved lightning was a form of electricity; Alessandro Volta inventing the first battery, which he called the "electric pile"; Thomas Edison developing the first commercial electric power distribution system using DC; and Nikola Tesla developing the AC power system still used today in order to transmit electricity over longer distances more efficiently than DC. The document outlines the contributions of many important figures that advanced humanity's understanding and practical application of electricity over centuries.
What a machine!
Benjamin Franklin discovered electricity in America in 1752. The first application of electricity was the light bulb, invented by Thomas Edison in 1879 to produce light. Electricity powers machines by moving atoms through wires from a battery's stored energy, allowing electricity to power devices like Edison's long-lasting light bulb for over 110 years.

It also covers concepts of electric charge, static electricity, electrical forces, grounding objects, and how lightning works by clouds building up an imbalance of electric charges with the ground.
Electricity caleb
Electricity is generated from coal power stations and windmills and travels through circuits which allow electrons to flow and power homes. Dams also help generate electricity as they harness energy from moving water which is then used to power homes through circuits that electrons flow through.
Nikola tesla
Nikola Tesla was a Serbian-American inventor, electrical engineer, and mechanical engineer born in 1856 in Austria-Hungary. He is known for his contributions to the design of the modern alternating current electricity supply system. Some of his most important inventions include the Tesla coil, which can generate high-frequency, high-voltage electricity, and his design for an induction motor. He demonstrated the feasibility of alternating current for power transmission systems, which helped establish AC as the standard for power transmission. Tesla died alone in a New York hotel room in 1943 at the age of 86.
Day one intro
Electrochemistry involves the flow of electrons between different metals. Luigi Galvani discovered that frog legs moved when touched with different metals, showing the connection between electricity and biology. Alessandro Volta found that two different metals in contact could generate electricity through the transfer of electrons from one metal to the other. He created the voltaic pile, consisting of alternating zinc and copper discs separated by cardboard soaked in brine, which produced a steady current. Later improvements included the Daniel cell and crowfoot cell, which used zinc and copper electrodes in a liquid electrolyte and were used for telegraph communications until the 1950s.
History of electricity
Ancient Egyptians observed shocks from electric fish as early as 2750 BC. Thales of Miletus documented static electricity from rubbing amber in 600 BC. Experimentation continued through the Middle Ages and Renaissance with discoveries of electricity from various substances and bodies. The 18th century saw advancements in generating electricity through friction and improvements to electrostatic machines. Michael Faraday's discovery of electromagnetic induction in the 1830s was a major breakthrough.
Electricity and inventions
Electricity is a form of energy that is created by the movement of electrons between atoms. In the 18th century scientists began studying electricity which led to many inventions in the 19th and 20th centuries, including those of Thomas Edison such as the electric light bulb. Electricity powers our modern world through electrical circuits which can be simple, series, or parallel and get energy from power stations to homes through cables and fuse boxes.
Electricity by tarang
Thomas Edison, Michael Faraday, and Benjamin Franklin were influential inventors and scientists in the fields of electricity and electromagnetism. Edison developed many devices that shaped the modern world, Faraday's discoveries included electromagnetic induction, and Franklin was a polymath who made important contributions to physics through his study of electricity. Natural electrical phenomena can be observed in forms like lightning and static electricity, and the Earth's magnetic field is generated by circulating currents in its core. Certain materials also demonstrate piezoelectricity, or the generation of electric charges when subjected to pressure.
Solar 101
Solar energy comes from the sun and can be used as a source of heat and light or to generate electricity. It has been harnessed for centuries through technologies like solar heating. Modern solar power plants use either photovoltaic cells or thermal systems to convert sunlight into electricity. A photovoltaic plant directly converts sunlight to electricity using solar arrays and inverters, while a thermal plant uses concentrated sunlight to heat a working fluid and drive a turbine generator. To power Arizona would require around 400 square miles of solar panels, capturing the abundant yearly sunshine to generate the state's electricity needs.
Wind energy
This document discusses wind and solar energy. It explains that wind energy is produced through wind turbines that convert the kinetic energy of wind into electrical energy. Solar energy is produced through solar panels that convert sunlight into electrical energy. Scotland is well suited for wind energy production due to its windy conditions. While renewable sources are cleaner than coal and nuclear, wind turbines have disadvantages such as high setup costs and effects on landscapes. The document considers pros and cons of different renewable energy sources.

History of electricity (3)
The Greeks discovered electricity in 600 BC by observing that rubbing fur and tree resin caused attraction. The first application of electricity was an electromagnet built in 1831 by Joseph Henry, which was used to lift heavy metals. Otto von Guericke invented the first electric machine in 1672, an electrostatic generator that produced sparks from a sulfur globe using energy from a piece of amber.

The document discusses the history of electricity and early electric machines. It describes how Alessandro Volta constructed the first electric battery called the "voltaic pile" in 1800, which consisted of alternating copper and zinc discs separated by brine-soaked cloth. The voltaic pile was one of the first electric machines built and generated electricity through a chemical reaction rather than a voltage difference between metals. Volta used his machine to decompose chemicals and produce new substances, demonstrating early applications of electricity.

Electricity is a form of energy that is created by the movement of electrons between atoms. In the 18th century scientists began studying electricity which led to many inventions in the 19th and 20th centuries, including those of Thomas Edison such as the electric light bulb. Electricity powers our modern world through electrical circuits which can be simple, series, or parallel and get energy from power stations to homes through wiring.
History of electricity
Benjamin Franklin's experiments with electricity in the 18th century were an early step, but consistent sources of electricity were still needed. Alessandro Volta invented the first battery in 1800, allowing scientists to reliably study electricity. Michael Faraday then discovered electromagnetic induction, the basis for electric generators. Thomas Edison developed a long-lasting incandescent light bulb in 1879. In 1882, Edison opened the first electric power plant in Manhattan, though electricity was still expensive. Alternating current systems were developed, allowing electricity to travel much farther than Edison's direct current plant.
Electricity and inventions
Electricity is formed by the movement of electrons between atoms. In the 18th century scientists began studying electricity which led to many inventions in the 19th and 20th centuries. Thomas Edison discovered ways to produce and use electricity commercially and invented devices like the light bulb which changed modern life. Electricity is transmitted through power lines from generation stations to homes where it powers devices through electrical circuits.
Electricity
Electricity was discovered in ancient Greece around 600 BC by Thales of Miletus, who observed that amber attracted some objects when rubbed. The first application for electricity in the 19th century was using steam, water wheels, and horses to generate it, with Joseph Henry inventing the horseshoe battery in 1829. One of the earliest electric machines built was the lightbulb, invented in 1879 by Thomas Edison using a carbon filament, which lasted around 13 hours in one of his first successful tests.

Electricity was discovered in ancient Greece around 600 BC by Thales of Miletus, who observed that amber attracted some objects when rubbed. The first application for electricity in the 19th century was using it for everyday life through machines powered by steam, water wheels, horses, and people. One of the first electric machines built was the lightbulb, invented in 1879 by Thomas Edison. The lightbulb used a carbon filament inside a glass bulb to produce light through an electrical current without combustion.
Introduction to electricity 1
Electricity occurs naturally but people invented ways to measure and control it. Early pioneers like Gilbert, Stoney, and Thomson discovered properties of electricity and atoms. Franklin proved lightning is electricity. Volta invented the battery, and Faraday discovered electromagnetic induction. Edison developed the incandescent light bulb for DC power, while Tesla invented the AC induction motor developed by Westinghouse, establishing AC as the dominant power system.
Project 1 What a machine!
The document discusses the history and development of the light bulb. It notes that Benjamin Franklin discovered electricity in 1752 and that the first application was lighting. The first lightbulb is still working after 109 years. The light bulb was invented by Thomas Edison in 1879, but a German watchmaker, Heinrich Göbel, developed a working light bulb in 1854 that lasted for 400 hours, making it earlier than Edison's. The document also explains that electricity comes from the movement of atoms in a conductive material connected to a battery, and that light bulbs transform this electrical energy into light.

The document discusses the early history and discovery of electricity. It notes that electricity was first discovered in ancient Greece around 600 BC by Thales of Miletus through observing static electricity from rubbing fur on amber. Key figures that later studied and advanced the understanding of electricity included Alessandro Volta, Michael Faraday, Benjamin Franklin for his kite experiment, and Thomas Edison who experimented with electricity to create the light bulb. One of the earliest applications was Joseph Henry's electromagnet in the 19th century and Pixii's magneto generator in 1832 which could produce electric current.
twtrwtrsrjihio'History of Electricity.pptx
The document summarizes the key contributions of scientists and inventors to the development of electricity. It describes how William Gilbert began the science of magnetism in the 1600s. In the 1700s, Benjamin Franklin conducted experiments with electricity and lightning. Luigi Galvani discovered that frog muscles twitch near an electrical machine. Alessandro Volta then invented the first battery in 1799. Many other scientists and inventors further advanced the understanding and applications of electricity throughout the 1700s-1900s, including Faraday, Ohm, Edison, Tesla, Maxwell, Hertz, and others. Their discoveries led to modern developments like the transistor and integrated circuit.
How the First Ever Light Bulb Was Invented
The document discusses the history of the light bulb, from early unsuccessful attempts in the 18th century to the breakthrough of Thomas Edison in the late 19th century. It describes experiments before Edison with electric arcs and carbon filaments that did not last long enough. Edison was eventually able to create a carbonized thread that burned for 13 hours in 1879, leading to his successful commercialization of the light bulb. While light bulbs are now commonplace, research continues to improve efficiency and performance.
sources of electricity: hydro power, solar power etc.
Electricity can be produced through various natural processes and human-made methods. Some key ways discussed include using moving water in hydroelectric dams, the heat from nuclear fission, and converting sunlight in solar panels. Thermal power plants predominantly burn fossil fuels to heat water and power steam turbines. Other renewable sources mentioned are wind turbines, geothermal energy from the earth's heat, and tidal barrages that capture ocean current energy.
ELECRICITY
Michael Faraday invented the electric generator in 1831, allowing electricity to light homes, roads, offices, markets and factories after sunset. This important invention changed the world by creating a new era where work could continue at night, powered by electricity. The document discusses how electricity generation through sources like solar, nuclear, hydro and wind transformed life after darkness fell each day.

Electrical basic engineering by Ramesh meti karanataka
Electricity was first discovered in 600 BC but scientific understanding began in the 18th century. Key discoveries included friction electricity by Thales in 600 BC, the word "electricity" coined in 1600, and the first chemical battery invented by Volta in 1800. Thomas Edison helped bring electricity to homes in New York in 1882, but most homes did not have power until 1925. Edison also invented the incandescent light bulb in 1879. Electricity starts at power plants, is transmitted through high voltage lines and substations, distributed through lower voltage lines, and finally enters homes through service drops. Proper safety precautions must be taken when working with electricity to avoid shock and fire.
Generation of electricity
Electricity is generated through various processes that convert other forms of energy into electrical energy. Historically, ancient Greeks discovered static electricity and Ben Franklin experimented with electricity using a kite. Modern generation uses processes like Faraday's law of induction. Common methods include burning fossil fuels in power plants to heat water and power steam turbines, using nuclear fission in nuclear plants, and harnessing the kinetic energy of moving water in hydroelectric dams. Renewable sources also generate electricity through technologies that convert wind, solar, tidal, and geothermal energy. Electricity is transmitted through power lines using alternating current of a standard frequency.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Artificial Intelligence for XMLDevelopment
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
