LC problem (15 points) (a) Find in full detail using the algebra-impedance-box approach the resulting alternating current in the circuit below (find the expression I (t)). Assume that the peak voltage of the emf alternating power supply is 340 Volts, take L=1Henri,C=1 Farad. Remember that in this class we are using V(t) = Vosin(wt) for the voltage out of the power supply (b) What is the exact amplitude of the alternating current I(w) when the frequency of the emf is 159.2 mHz? switch closed at t = 0 N = L 1 H SW V C sine 1 F 159.2 miz
