Question
Two batteries A and B are joined in parallel.
Connected across the battery terminals is a circuit consisting of a battery C in series with a 25 Ω resistor, the
negative terminal of C being connected to the positive
terminals of A and B. Battery A has an e.m.f. of 108 V
and an internal resistance of 3 Ω, and the corresponding
values for battery B are 120 V and 2 Ω. Battery C has
an e.m.f. of 30 V and a negligible internal resistance.
