Question

14. RLC Series Circuit. In the study of an electrical circuit consisting of a resistor, capacitor, inductor, and an electromotive force, we are led to an initial value problem of the form L dI/dt + RI + q/C = E(t) q(0) = q0, I(0) = I0. where L is the inductance in henrys, R is the resistance in ohms, C is the capacitance in farads, E(t) is the electromotive force in volts, q(t) is the charge in coulombs on the capacitor at time t, and I = dq/dt is the current in amperes. Find the current at time t if the charge on the capacitor is initially zero, the initial current is 0, L = 10henrys, R = 20ohms, C = 6260^-1farads and E(t) = 100volts. Hint: Differentiate both sides of the differential equation to obtain a homogeneous linear second order equation for I(t). Then use equation (1) to determine dI/dt at t = 0.
