Two batteries A and B are connected in parallel and load of 10Ω is connected across their terminals. A has an e.m.f of 12 V and an internal resistance of 2Ω. B has an e.m.j.of 8 V and A an internal resistance of 1Ω. Use Kirchhoff's laws to determine the values and directions of the currents flowing in each of the batteries and in the external resistance. Also determine the potential difference across the external resistance.
