Phase Difference in AC Circuits

Match List-I with List-II

List-I	List-II
A. Phase difference between current and voltage in a purely resistive AC circuit	1. ‌ π 2 ; current leads voltage
B. Phase difference between current and voltage in a pure inductive AC circuit	2. Zero
C. Phase difference between current and voltage in a pure capacitive AC circuit	3. ‌ π 2 ; current lags voltage
D. Phase difference between current and voltage in an L−C−R series circuit	4. tan−1(‌ XC−XL R )
