In series L-C-R circuit the quality factor is

Resonance in series LCR circuit and quality factor

In a series L-C-R circuit At resonance quality factor is 100. Now value of self inductance doubled and resistance is decreased two fold then find new value of quality factor.

For series LCR circuit,quality factor at resonance will be (symbols have their usual meaning)

Obtain an equation for sharpness of resonance in an L-C-R series AC circuit and what is quality factor Q ? And explain bandwidth.
