Physics (AS & A Level) · Feb / March 2024 · Paper 12 · Question 35
The diagram shows a cell with internal resistance connected in parallel with a fixed resistor and a variable resistor. The resistance of the variable resistor is decreased. What happens to the potential difference V across the variable resistor and the current I in the variable resistor?
- AV decreases, I decreases
- BV decreases, I increases
- CV increases, I decreases
- DV increases, I increases
As printed in the paper
