JEE Main Physics Class 12 Alternating Currents Part 1 Questions

A. In a purely resistive AC circuit, the phase difference between the current and voltage is zero.
B. In a purely inductive AC circuit, the current lags the voltage, so the phase difference between the current and voltage is π∕2.
C. In a purely capacitive AC circuit the current leads the voltage, so the phase difference between the current and voltage is π∕2.
D. The phase difference between current \& voltage in an L−C−R series circuit is
φ=tan−1‌

(XC−XL)

R

∴ The correct match is A-(2), B-(3), C-(1), D-(4).
