Physics (AS & A Level) · May / June 2017 · Paper 11 · Question 35

The circuit shown includes a cell of constant internal resistance and an external resistor R. A student records the ammeter and voltmeter readings. She then connects a second identical external resistor in parallel with the first external resistor. What happens to the ammeter reading and to the voltmeter reading?

1. Aammeter reading decreases, voltmeter reading decreases
2. Bammeter reading decreases, voltmeter reading stays the same
3. Cammeter reading increases, voltmeter reading decreases
4. Dammeter reading increases, voltmeter reading stays the same
