3. Two batteries A and B are connected in parallel and load of 10 N is connected
across their terminals. A has an e.m.f. of 12 V and an internal resistance of 2 2 ;
B has an e.m.f. of 8 V and an internal resistance of 1 Q. 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.
