(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 $${\pi \over 2}$$; current lags voltage.
(c) phase difference b/w current & voltage in a pure capacitive AC circuit is $${\pi \over 2}$$; current lead voltage.
(d) phase difference b/w current & voltage in an LCR series circuit is = $${\tan ^{ - 1}}\left( {{{{X_C} - {X_L}} \over R}} \right)$$
