Question

deduce the phase relationship between current and voltage in an AC circuit containing inductor only​

Answer 1

The phase relationship between current and voltage in an AC circuit containing only inductor is that voltage always leads the current flowing through the circuit by 90 degree or pi/2 radians.

When a sinusoidal input is provided to the circuit, the current increases from zero to the maximum value. This will give rise to generation of back e.m.f in the inductor. But voltage changes its polarity which in turn changes the direction of flow of current. But due to Lenz's law, the change in current direction gets further delayed.
