1

Which circuit component pushes charges (electrons) around a circuit?

Cells or batteries

2

The push given to charges, to make them move around a circuit can also be called the...

potential difference (p.d)

3

A charge that has been pushed with a lot of force is said to have a ______ potential difference.

large

4

A charge that has been pushed with a small force is said to have a ______ potential difference.

small

5

What do we use to measure potential difference (the amount of 'push' charges have around a circuit)?

a voltmeter

6

What are the units of potential difference (the amount of push a charge has as it moves around a circuit)?

Volts

7

The amount of push that a battery or cell can give to charges (electrons) in a circuit is called the...

Potential difference

Rating

Voltage

8

How would you connect a voltmeter to measure the potential difference in this circuit?

Always connect the voltmeter in 'parallel' aross the component you want to measure the potential difference of.

9

How can you increase the potential difference (push) of a circuit?

Add more cells (make a bigger battery)

10

What is meant by the 'rating' of a circuit component?

The rating tells you have much potential difference (push) the component is designed to work at.
