A resistor (20 Ω) and capacitor (0.1 F) are joined in series with an electromotive force (emf) E = E(t), as shown in Figure, If there is no charge on the capacitor at time t = 0, find the ensuing charge on the capacitor at time t for the given emf in the Exercise

Figure An RC circuit

E(t) = 100 V
