What this practice covers
These questions are drawn from past CIE 0625 Physics papers and filtered to electrical quantities. 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 electrical quantities, taken from our own topic notes. Read them before you practise and you will recognise the traps in the questions.
- Saying an object becomes positively charged by gaining protons.
- Connecting an ammeter in parallel or a voltmeter in series.
- Saying electrons flow from positive to negative, or that conventional current flows negative to positive.
- Leaving a time in minutes or hours when calculating energy in joules.
- Reading resistance as the gradient of a curved I-V graph.
- Saying a filament lamp's resistance falls as it heats.
- Confusing e.m.f. with potential difference: one supplies energy, the other transfers it away.
- Saying a thicker wire has more resistance.
