The RLC circuit in Figure is in the zero state when at t = 0 an exponential source, vS(t) = VAe-αt V, is suddenly connected to it.
(a) Find the circuit integrodifferential equation that describes the behavior of the current in the circuit.
(b) If R = 82 Ω, L = 100 mH, C = 15 μF, VA = 15 V, and α = 500 s-1, use Laplace transforms and MATLAB to solve for i(t) for t ≥ 0:
