KCET · Physics · Alternating Current
For a series circuit at resonance, the statement which is not true is
- A Peak energy stored by a capacitor = peak energy stored by an inductor.
- B Average power = apparent power.
- C Wattless current is zero.
- D Power factor is zero.
Answer & Solution
Correct Answer
(D) Power factor is zero.
Step-by-step Solution
Detailed explanation
For a series circuit at resonance
Phase difference, \(\phi=0^{\circ}\)
Power factor \(=\cos \phi=1\).
Phase difference, \(\phi=0^{\circ}\)
Power factor \(=\cos \phi=1\).
