Electrical Current is the amount of electricity flowing through a wire.

The bigger the electrical current the brighter a bulb and the louder a buzzer.

If an electrical current goes through an animal it is called an electrical shock.

An electrical current is a flow of charge.

Current is measured using an Ammeter.

The units of current are amperes, which are also called amps (A).

A current in a wire is a flow of electrons which are negatively charged particles.

Conventional Current flows from positive to negative. This is because electricity was discovered before scientists knew about electrons.

In a salt solution current is the flow of both positive and negative ions.
