Since the current is I = switch The figure above shows a circuit containing an electromotive force (a battery), a capacitor with a capacitance of C farads (F), and a resistor with a resistance of R ohms (). The voltage drop across the capacitor is Q/C, where is the charge (in coulombs), so in this case Kirchhoff's Law gives W dQ dt ' . R we have RI+ Find the charge and the current at time t. Q(t) = I(t) = dQ dt R- Q с = : E(t). Suppose the resistance is 20 , the capacitance is 0.2F, a battery gives a constant voltage of E(t) = 60V, and the initial charge is Q(0) = 0C + + Q = E(t).
