In a series resonant L–C–R circuit, if L is increased by 25% and C is decreased by 20%, then the resonant frequency will –

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

In a series resonant L-C-R circuit, the capacitance is changed from C to 3C. For the same resonant frequency, the inductance should be changed from L to

In a series resonant L-C-R circuit, the capacitance is changed from C to 3C. For the same resonant frequency, the inductance should be changed from L to

In series L-C-R resonant circuit, to increase the resonant frequency

In an LCR series resonant circuit, the capacitance is changed from C and 4C. For the same resonant frequency,the inductance should be changed from L to:
