Physics Reference: A battery of electromotive force (e.m.f.) E and internal resistance 1.5 Ω is connected to a network of resistors, as shown in Fig. 6.1.
Suppose the emf of the battery in the circuit shown in Figure varies with time t so that the current is given by i(t)=3.0 + 5.0t, where i is in amperes and
