Answer 1

In case of pure resistive circuit, the phase angle between voltage and current is zero i.e. both are in phase.
In case of pure capacitive circuit, phase angle is 90° i.e. current leads the voltage by 90°.
In case of series RC circuit, the phase angle is resultant of both resistance and capacitance. This will be varies from 0 to 90° based on the values of resistance and capacitance and AC current leads the voltage by an angle in between 0 to 90°
In pure inductive circuit, the current lags the voltage by 90°
In series RL circuit, the current lags the voltage by an angle in between 0 to 90°
