A series LCR circuit contains a pure inductor of inductance 5.0H, a capacitor of capacitance 20mu F and a resistor 40Omega . Find the resonant frequency of the circuit. Calculate the quality factor (Q- factor ) of the circuit. What is the impedance at resonant condition?

.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
