12. A diode circuit with an LC load is shown In the following figure, with the capacitor having an initial voltage Vê(t=0) = -Vco = Vo-220 V, capacitance, C = 20 uF; and inductance, L = 80 uH. If switch S₁ is closed at t=0, determine (a) the peak current through the diode, (b) the conduction time of the diode, and (c) the final steady-state capacitor voltage. S₁ L ✗D₁
