Question: Power factor is maximum in an LCR circuit when [RPET 2000]
Options:
A) $ X_{L}=X_{C} $
B) $ R=0 $
C) $ X_{L}=0 $
D) $ X_{C}=0 $
Show Answer
Answer:
Correct Answer: A
Solution:
In LCR circuit; in the condition of resonance $ X_{L}=X_{C} $ i.e. circuit behaves as resistive circuit. In resistive circuit power factor is maximum.
