We measure electricity by the that flows around a circuit. In a simple circuit with a bulb, a sm flowing around it will produce a light. If a flows around this same circuit then the light will be much .

The amount of flowing through a circuit is measured using an . The units for current is called the or ps for short. It is also written as a simple .

It is important to remember that the current travels round and the circuit. It is not .

What then is an ?

It is actually the and in doing so carries .

All matter is made up of particles called . have even smaller particles inside them called . In some materials like metals these can easily travel from one to another. This allows an these materials. Such materials like metals are called .

In the case of materials like plastic the cannot around so a rent can f through.
