a. Explain the difference between potential difference and e.m.f.

b. A battery has negligible internal resistance, an e.m.f. of 12.0 V and a capacity of 100 A h (ampere-hours). Calculate:

i. The total charge that it can supply

ii. The total energy that it can transfer.

c. The battery is connected to a 27 W lamp. Calculate the resistance of the lamp.
