JEE Main 2022 — Alternating Current Question with Solution

JEE Main 2022 (25 Jul Shift 1)

Question

To increase the resonant frequency in series LCR circuit,

Choose an option

Show full solutionCorrect option: C
Correct answer
CAnother capacitor should be added in series with the first capacitor

Step-by-step explanation

The resonant frequency of an LCR circuit is given by f=12πLC. It does not depend on the source frequency as well as the resistance of the circuit.

Therefore, to increase the resonating frequency product of L and C should decrease.

By joining another capacitor in series, the equivalent capacitor will decrease.

Hence, option C is correct option.
