What is electricity?

Electricity is a form of energy created when sub-atomic particles called electrons flow from place to place.

An electrical charge refers to when these electrons build-up on an object but cannot flow further. This can be released as static electricity if touched by another object that can conduct electricity.

An electric current refers to the electrons flowing from one place to another, normally within a form of electrical circuit.

Lightning is really a very powerful and natural electric "spark" caused by thunderstorms. Electrical charges build up around thunderclouds until they can be released, either between clouds, or between clouds and the ground. When that happens, a sudden and quick electric current flows, resulting in a brilliant light flashing across the sky. Learn more about lightning around Australia .
