Extracted text: Two batteries A and B are connected in parallel and a load of 10 ohms is connected across their terminals. A has an e.m.f. of 12 V and an internal resistance of 2 ohms ; B has an e.m.f. of 8 V and an internal resistance of 1 ohm. 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.
