A cell that has internal resistance is joined to a light-dependent resistor (LDR), a fixed resistor and a voltmeter, as shown. The voltmeter reading rises. Which quantity falls as the voltmeter reading rises?
- Athe charge moving through the cell per unit time
- Bthe energy transferred to the fixed resistor per unit charge
- Cthe intensity of the light incident on the LDR
- Dthe terminal potential difference across the cell
