Power in AC Circuits Examples

In resonant circuit, at resonant frequency

Assertion : In series L-C-R, AC circuit, current and voltage are in same phase at resonance. Reason : In series L-C-R, AC circuit, resonant frequency does not depend on the value of resistance. Hence, current at resonance does not depend on resistance.

In LCR circuit currnet resonant frequency is 600Hz and half power points are at 650 and 550 Hz. The quality factor is

In a series LCR circuit resonance of frequency is the half of the frequency of source.The nature of the circuit is

In a series LCR circuit, the resonance frequency is 800 Hz. The half power points are obtained at frequencies 745 and 855 Hz. Calcualte the Q factor of the circuit and the band width.
