The phase differnece between the current and the voltage in series LCR circuit as resonance is

What is the differnece between steady current and d.c.?

A capacitor with capacitance C and a coil with active resistance R and inductance L are connected in series to a source of sinusoidal voltage of frequency omega . Find the phase difference between the current fed to the circuit and the source voltage.

An LCR-circuit is connected to a source of a.c. current under resonant condition. The phase difference between the applied voltage and the current it the circuit is

An a.c. Voltage is applied to a resistance R=30 Omega and an inductor L in series. If the inductive reactance is also 30 Omega , the phase difference between the applied voltage and the current in the circuit is
