Q. For a series L-C-R 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) Wattles current is zero
D) Power factor is zero
Explanation
(d) For a series L – C – R
circuit at resonance
Phase difference, $\phi = 0{^\circ}$
Power factor$= \cos{\phi = 1}$
