In a circuit L, C and R are connected in series with an alternating voltage source of frequency f. when current in the circuit leads the voltage by 45circ the value of C.

When a capacitor of small capacitance is connected in series with L-R circuit. The alternating current in the circuit increases. Explain why ?

An AC circuit contains a resistance R, an inductance L and a capacitance C connected in series across an alternator of constant voltage and variable frequency. At resonant frequency, it is found that the inductive reactance, the capacitive reactance and the resistance are equal and the current in the circuit is i_(0) . Find the current in the circuit at a frequency twice that of the resonant frequency.
