MCQ
Power factor is maximum in an $LCR$ circuit when
- ✓${X_L} = {X_C}$
- B$R = 0$
- C${X_L} = 0$
- D${X_C} = 0$
✓
Answer
Correct option: A.
${X_L} = {X_C}$
a
(a)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.
