A cell that has a constant electromotive force (e.m.f.) is connected to a fixed resistor. With time, the cell’s internal resistance rises. What happens when the internal resistance rises?
- Aa decrease in the charge of each charge carrier
- Ba decrease in the potential difference measured across the cell
- Can increase in the energy dissipated per unit time in the fixed resistor
- Dan increase in the number of charge carriers leaving the cell per unit time
