MHT CET 2023 Physics question

An alternating voltage is applied to a series LCR circuit. If the current leads the voltage by 45°, then ()

(A)Correct
(B)
(C)
(D)

Answer: (A)

Solution

In a series LCR circuit the phase angle satisfies (positive when voltage leads current). Current leading the voltage by means the circuit is capacitive, so and . Hence $=-1⇒ -=-R⇒
