(a) In a series LCR circuit connected across an AC source of varible frequency, obtain the expression for its impedance and draw a plot showing its variation with frequency of the AC source.
(b) What is the phase differene between the voltages across inductor and the capacitor at resonance in the LCR circuit ?
(c ) When and inductor is connected to a 200 V DC voltage, a current of 1Aflows trough it. when the same inductor is connected to a 200 V, 50 Hz AC source, only 0.5 A current flows. Explain, why ? Also, calculate the self inductance of the inductor.
