(1 point) E 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 Rohms (N). The voltage drop across the capacitor is Q/C, where is the charge (in coulombs), so in this case Kirchhoff's Law gives = E(t). Since the current is I = dQ dt R we have RI+ dQ R + dt 1 Q = C E(t). Suppose the resistance is 30, the capacitance is 0.15F, a battery gives a constant voltage of E(t) = 50V, and the initial charge is Q(0) = 0C. Find the charge and the current at time t. Q(t) = I(t) =
