1. Use Laplace Transforms to determine the function modeling the current in an RLC circuit with L10 Henries, R = 20 ohms, C = 0.02 Farads, the initial charge is Q(0) = 0, the initial current is I (0) = 0, there is an electromotive force forcing the RLC circuit via the voltage function E(t) = 10 sin(t), and then, at t = 27 seconds, the battery is turned off, letting the current alternate naturally through the circuit. Use the fact the differential 1 d²Q dQ equation L +R dt² dt +2= (1 - U27 (t)) 10 sin(t –27) to find the solution for Q(t) and then take its derivative to find I(t). Be careful of discontinuities when taking the derivative. Graph both Q and I using your favorite software and attach them.
