Q 12-07-083JEE MainJEE Main 2023 (12 Apr, Shift 1)Easy
Given below are two statements:
**Statement I:** When the frequency of an AC source in a series LCR circuit increases, the current in the circuit first increases, attains a maximum value and then decreases.
**Statement II:** In a series LCR circuit, the value of power factor at resonance is one.
In the light of given statements, choose the most appropriate answer from the options given below.
Answer: (C) Both Statement I and Statement II are correct
The current peaks at the resonant frequency (I correct), where $Z=R$ and the power factor $\cos\phi=1$ (II correct).
