Correct answer
A(a)-(ii), (b)-(iii), (c)-(i), (d)-(iv)
Step-by-step explanation
(a) phase difference b/w current & voltage in a purely resistive AC circuit is zero
(b) phase difference b/w current & voltage in a pure inductive AC circuit is ; current lags voltage.
(c) phase difference b/w current & voltage in a pure capacitive AC circuit is ; current lead voltage.
(d) phase difference b/w current & voltage in an LCR series circuit is =
