A series circuit contains a resistor with R = 120 Ohm, an inductor with L = 10 H, a capacitor with C = 0.001 F, and a 12 V battery. The initial charge is Q = 0.002 C and the initial current is 0. Find the charge and current at time t. Q(t) = I(t) = A series circuit consists of a resistor with R = 20 Ohm, an inductor with L = 1H, a capacitor with C = 0.005 F, and a generator producing a voltage of E(t) = 12sin(20t). If the initial charge and current are both 0, find the charge at time t. Q(t) = A series circuit contains a resistor with R = 16 Ohm, an inductor with L = 2 H, a capacitor with C = 0.02 F, and a generator producing a voltage of E(t) = 12sin(5t). The initial charge is Q = 0.003 C and the initial current is 0. Find the charge at time t. Q(t) = C
