List of top Physics Questions on Power factor asked in TS EAMCET

If a resistor of resistance \(30\,\Omega\) and an inductor of reactance \(40\,\Omega\) are connected in series to an AC source of peak voltage \(200\sqrt2\,\mathrm{V}\), then the average power loss over a complete cycle is

In an ac circuit, if the rms value of current is 2 A and the wattless current is \(\sqrt{3}\) A, then the power factor of the circuit is
