If the frequency of the source e.m.f. in an AC circuit in n ,the power varies with a frequency:

If the frequency of the source e.m.f. in an AC circuit in n ,the power varies with a frequency:

If the frequency of alternating e.m.f. is in L-C-R circuit, then the value of impedance Z will change with log (frequency) as

Power in an ac circuit | Resonant frequency

In a series LCR circuit with value of R = 15 Omega , L = 5 H , C = 100 muF an AC power supply with variable frequency is connected . Calculate the value of angular frequency of the source at which the circuit is in resonance and current at the same frequency . The V_("rms") value of voltage in the circuit is 220 V.

A variable frequency AC source is connected to a capacitor. Then on increasing the frequency

Frequency of AC source is continuously increased, impedance of LCR series circuit

A series LCR circuit containing 5.0 H inductor, 80 mu F capacitor and 40 Omega resistor is connected to 230 V variable frequency ac source. The angular frequencies of the source at which power transfered to circuit is half the power at resonant angular frequency are likely to be.

How does inductive reactance vary when frequency of a.c. source in the circuit is halved ?
