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.

.In a series LCR resonant circuit,the quality factor is measured as "100" .If the inductance is increased by two fold and resistance is decreased by two fold,then the quality factor after this change will be

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

In L-C-R series circuit

A series resonant LCR circuit has a quality factor (Q-factor)=0.4. If R=2k Omega, C=0.1 mu F then the value of inductance is

In a series resonant L-C-R circuit, the power factor is

If V_0 and I_0 are the peak current and voltge across the resistor in a series L-C-R circuit, then the power dissipated in the circuit is (power factor =costheta)

In the series L-C-R circuit , the voltmeter and ammeter readings are respectively
