3. Consider an RLC circuit with R = 30 ohms , L = 10 henry (H), and C= 0.02 farad (F). At time t = 0, when both I(0) and Q(0) are zero, the switch in the circuit is closed and an alternating current given by E(t) = 50 sin(2t) is allowed into the circuit. Find the current in the cuircuit and the time lag of the steady periodic current behind the voltage.
