MHT CET 2025 Physics question

L, C and R are connected in series to an a.c. source. Which one of the following is true?

Phase relation between current and voltage is such that

(A)both are out of phase with each other in 'R'
(B)both are in phase in 'L' and out of phase in 'C'
(C)both are out of phase in 'L' and in phase in 'C'
(D)both are out of phase in both 'C' and 'L'.Correct

Answer: (D)

Solution

In a purely resistive element, voltage and current are in phase (phase difference 0), so (A) is false. In an inductor the voltage leads the current by , so they are out of phase; in a capacitor the voltage lags the
