Current (Amps) 

The flow of electrons round the circuit. Current will only flow through a component if there is a voltage accross it.

Voltage (Volts)

The difference in electrical potentail between two points


The electrical state of an object - It can be positive, negative, or neutral

Resistance (Ohms)

Anything in the circuit which slows the flow down.

If you increase the voltage the more current will flow.

If you increase the resistance the less current will flow.

Step-up transformer

Increases voltage and decreases current
