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.

3. ELECTRICITY
a form of energy resulting from the existence of
charged particles (such as electrons or protons), either
statically as an accumulation of charge or dynamically
as a current.
Electricity is the presence and flow of electric charge.
Using electricity we can transfer energy in ways that
allow us to accomplish common chores. Its best-known
form is the flow of electrons through conductors such
as copper wires. It is a form of energy which we use to
power machines and electrical devices.

4. THREE MAJOR CATEGORIES of Energy
for Electricity generation
1. Fossil Fuels (coal, natural gas, and petroleum)
2. Nuclear Energy
3. Renewable Energy sources. Most electricity is
generated with steam turbines using fossil fuels,
nuclear, biomass, geothermal, and solar thermal
energy.

5. Electricity sources are defined as the resources
for electric power.

7. HISTORY
 For thousands of years, people all over the world have been fascinated by lightning. Some people
must have wondered how to put that kind of power to practical use. But it wasn't until the 18th
century that the path to the everyday use of electrical power began to take shape.
 Benjamin Franklin. In 1752, to prove that lightning was
electrical, he flew a kite during a thunderstorm.
 Ben Franklin proved that lightning was a form of electricity.
 famous kite experiment by American Founding Father and inventor
 He tied a metal key onto the string and, as he suspected it would, electricity from the storm
clouds flowed down the string, which was wet, and he received an electrical shock. Franklin was
extremely lucky not to have been seriously hurt during this experiment, but he was excited to
have proved his idea.

8.  Throughout the next hundred years, many inventors and scientists tried to find a
way to use electrical power to make light. In 1879, the American inventor Thomas
Edison was finally able to produce a reliable, long-lasting electric light bulb in his
laboratory.
