A battery is connected in series with a resistor R. The battery transfers 2 000 C of charge
completely round the circuit. During this process, 2 500 J of energy is dissipated in the resistor
R and 1 500 J is expended in the battery.
The emf of the battery is
A. 2.00 V.
B. 1.25 V.
C. 0.75 V.
D. 0.50 V.
