What is electricity?
Quick Answer
Electricity is the flow of electric charge, usually carried by electrons moving through a material such as a metal wire.
The Full Story
Electricity is a form of energy created by the movement of electric charge. In most everyday cases, that means electrons drifting through a conductor like copper wire when a voltage pushes them along. This flow, called current, can power devices, produce heat and light, and create magnetic fields. Electricity occurs naturally too — lightning is a giant electrical discharge, and nerve signals in your body are tiny electrical pulses. Harnessing it reliably transformed the modern world.
