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.

Explanation

Here, `v_(r) = 800 Hz, v_(1) = 745 Hz, v_(2) = 855 Hz`
`Q = (v_(r))/(v_(2) - v_(1)) = (800)/(855 - 745) = (800)/(110) = 7.27`
Band width ` = v_(2) - v_(1) = 855 - 745 = 110 Hz`
