What this practice covers
These questions are drawn from past CIE 0654 Co-ordinated Sciences papers and filtered to electricity and magnetism. You answer, you find out immediately whether you were right, and you get the reasoning for the correct option and for each distractor. Wrong answers go to a mistakes locker so you can come back to exactly those.
Practice is free. You need an account only so your progress and your mistakes are still there next time.

What examiners see students get wrong here
These are the errors that cost marks on electricity and magnetism, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Putting the ammeter in parallel or the voltmeter in series.
- Saying current is used up as it goes round a circuit. It is the same all the way round a series circuit.
- Saying parallel resistors give a larger total resistance.
- Putting the fuse in the neutral wire.
- Saying a transformer works on direct current.
- Saying a potential difference is induced while a magnet sits still inside a coil.
- Saying high-voltage transmission reduces losses because voltage is lost. It is the current that matters.
Revise it first
