When static electricity builds up from friction between a wool hat and hair, the electrons move from the hair to the hat, leaving the hair with a positive charge that causes it to stand up. Conductors like metals allow electricity to flow through, while insulators like plastic and glass restrict electricity flow. Circuits can be open or closed, and wired in series where electricity passes through components one after the other, or parallel where it passes through simultaneously.

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.
Intro to electricity cristina hernandez
Electricity is produced when electrons move between atoms. It is everywhere in electrical outlets, batteries, and static electricity from rubbing your feet on carpet. An electric circuit allows electrons to flow continuously from a power source like a battery through a conductor like a wire back to the source. Conductors freely allow electron movement while insulators do not, preventing shocks. Electricity can be static and stay in one place or use current to flow through closed circuits in appliances, creating alternating currents.

Multiple transistors would need to be connected in series to increase the voltage output.
Home Solar System Must Know Tips
The key components of a solar panel system include photovoltaic cells, solar panels, a solar power system, proper orientation, and an inverter. Photovoltaic cells convert sunlight into electricity, solar panels house multiple cells, and connecting several panels creates a solar power system. For maximum efficiency, the panels must be oriented in the direction with the greatest solar potential. An inverter is also needed to transform the direct current from the panels into alternating current that can power household appliances. Consulting a professional is recommended to determine the appropriate components for a specific application.

- Electricity is the flow of electrons in a circuit powered by a battery or other energy source. An electric current is measured in amps and is the rate of flow of electric charges.
- Circuits can be arranged in series or parallel. A series circuit has components connected one after the other, while a parallel circuit splits into two or more branches.
- Other concepts covered include electric fields, voltage, resistance, and the relationships between current, voltage, power, and resistance defined by Ohm's law. Hands-on modeling of electric circuits used "pretzels" representing electrons.
Build a Simple Electric Motor
This document describes the design and construction of a simple electric motor. The author aimed to improve upon a similar "Beakman's motor" design by addressing potential weaknesses like long spans between support brackets and small contact areas. The summary describes the materials used, step-by-step instructions, and tips for troubleshooting if the motor does not run properly.
07 dc motor
1) The document provides instructions for building a simple DC motor using magnet wire, a magnet, styrofoam base, battery, paperclips, and test leads.
2) It explains that a motor works by applying a current to a coil of wire in a magnetic field, which induces a force that causes the coil to spin.
3) To get continuous spinning, the instructions say to remove the enamel coating from half of the wire so that current only flows for half of each revolution, providing consistent force to keep the motor spinning.

electromagnetism
This document provides information on learning outcomes, misconceptions, and a brief history of magnetism and electromagnetism. The key learning outcomes are to describe the behavior of permanent magnets and how magnetic fields arise from moving charges. The brief history section outlines important discoveries and developments in electromagnetism from 1600 to the 1860s, including Oersted's discovery relating electricity and magnetism. Misconceptions discussed include that all metals are magnetic and that static charges interact with magnet poles.
Q3-Cirvuits_Week 5_Science 5.pptx
This document provides instructions for creating a parallel circuit in two different ways. The first method is simpler and uses aluminum foil and light bulbs, intended for younger students. It involves connecting strips of foil from a battery to two light bulbs in parallel. The second method uses wire, a switch, and may be more suitable for older students as it requires stripping insulation from wires. It involves connecting a battery, two light bulbs, and a switch in a parallel circuit using several pieces of wire. Both methods explain how to connect the necessary components to form a working parallel circuit that will light up both bulbs.
2 home wiring
This document provides instructions and diagrams for basic home electrical wiring projects. It begins with an overview of electrical safety and turning off the main power supply. It then discusses the different ways to add new circuits to an existing circuit breaker box. Several pages cover best practices for wiring outlets, switches, and lights using both metal and plastic electrical boxes. Diagrams show how to wire devices like single pole switches, three-way switches, and outlets. The document also includes information on wire sizes and capacities, as well as electrical terms and symbols.
Home wiring basics
This document provides instructions and diagrams for basic home electrical wiring. It includes information on safely turning power off, installing wiring in walls, wiring outlets and switches, and using wire nuts and screws. Diagrams show wiring configurations for outlets, switches, and junction boxes using proper wire colors and grounding techniques. Safety tips are provided throughout regarding turning power off before working and avoiding electrical hazards.
CBSE Class 12 Physics Investgatory Project file "SIMPLE DC MOTOR"
This document is a certificate for a student who completed an activity file on building a simple DC motor. It includes sections on the anatomy, physiology, construction, and troubleshooting of a basic DC motor. The motor uses a battery, wire coils, paper clips, and a magnet to generate rotation from electrical current. It works by applying the right hand rule to determine the direction of force on the coils from the magnetic field, causing the rotor to spin continuously.
