In LCR - circuit if resistance increases, 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.

If resistance is increased gradually in LCR circuit.

In LCR series circuit if the frequency is increased, the impendance of the circuit

A : A series resonant circuit is also known as an acceptor circuit. R : For large value of Ohmic resistance, the quality factor of a series resonant circuit is high.

The quality factor of LCR circuit having resistance ( R ) and inductance ( L ) at resonance frequency (omega ) is given by
