AQA GCSE Physics (9-1): Series Circuits.

Answers:
1) a) Current is the same everywhere in the circuit, so ammeter 2 also reads 5A.
b) i - both resistors will take half of the potential difference, so voltmeter 1 reads 5V.
ii - voltmeter 2 will also read 5V.
iii - The third voltmeter is attached across both resistors, so it will measure a potential difference of 10V.
