Which circuit component pushes charges (electrons) around a circuit?
Cells or batteries
The push given to charges, to make them move around a circuit can also be called the...
potential difference (p.d)
A charge that has been pushed with a lot of force is said to have a ______ potential difference.
A charge that has been pushed with a small force is said to have a ______ potential difference.
What do we use to measure potential difference (the amount of 'push' charges have around a circuit)?
What are the units of potential difference (the amount of push a charge has as it moves around a circuit)?
The amount of push that a battery or cell can give to charges (electrons) in a circuit is called the...
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.
How can you increase the potential difference (push) of a circuit?
Add more cells (make a bigger battery)
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.
