A simple introduction!Electricity is a fundamental part of nature and a common form of energy. It is the movement of electrons between two points, which creates an electric current. Here are some facts about electricity:
How it's generated
Electricity is produced by converting primary energy sources like coal, natural gas, nuclear energy, solar energy, and wind energy.
How it's used
Electricity is used in many modern technologies, including electric power and electronics.
How it's measured
The movement of electrons is called current, which is measured in amperes (I). The power available to push electricity around a circuit is measured in volts (V). Electrical power is measured in watts, which is obtained by multiplying amps by volts.
How it's conducted
For electricity to flow, there needs to be something conducting it. Insulators like rubber, wood, or cloth stop the flow of electricity.
How it's related to magnetism
Electricity and magnetism are both part of the phenomenon of electromagnetism.
How it's related to other phenomena
Lightning, static electricity, electric heating, and electric discharges are all related to electricity.
History
The idea of electricity may have been known to the Greek philosopher Thales of Miletus around 600 B.C. The first scientific study of electricity was done by the English physician William Gilbert in 1600.
