1
Q

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

A

Cells or batteries

2
Q

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

A

potential difference (p.d)

3
Q

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

A

large

4
Q

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

A

small

5
Q

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

A

a voltmeter

6
Q

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

A

Volts

7
Q

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

A

Potential difference

Rating

Voltage

8
Q

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

A

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

9
Q

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

A

Add more cells (make a bigger battery)

10
Q

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

A

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