Key Stage 2

Meaning

Voltage is how much push electricity has.

About Voltage

The bigger the voltage the more push the electricity has to go around the circuit.
Adding another cell to the circuit in series will increase the voltage.
With a bigger voltage a lamp will be brighter and a buzzer will be louder.

A series circuit with one cell and one bulb. A bulb will be brighter if the voltage is higher.

Key Stage 3

Meaning

Potential Difference is how much energy is transferred by a current.

About Potential Difference

Potential Difference is measured using a Voltmeter.
The units of potential difference are Volts (V).
Potential Difference is sometimes described as the 'push' that moves a current around a circuit.
