In an LCR series circuit, at resonance
In an LCR series circuit, at resonance
Show Hint
At resonance, an LCR circuit behaves as a purely resistive circuit. This is why the power factor (\( \cos \phi \)) is equal to 1.
Updated On: May 6, 2026
- the current and voltage are in phase
- the impedance is maximum
- the current is minimum
- the quality factor is independent of R
- the current leads the voltage by \( \frac{\pi}{2} \)
Show Solution
The Correct Option is A
