Physics (AS & A Level) · May / June 2024 · Paper 13 · Question 36

The diagram shows a circuit consisting of a cell and three resistors R1, R2 and R3. The cell has electromotive force (e.m.f.) 1.60 V and negligible internal resistance. The current in the cell is 0.64 A. The potential difference across R1 is 0.48 V. The current in R3 is 0.32 A. What is the resistance of R2?

1. A1.5 Ω
2. B2.5 Ω
3. C3.5 Ω
4. D5.0 Ω
