An inductor of inductance \( \mathrm{L} \) and resistor of resistance
\( \mathrm{P} \) \( \mathrm{R} \) are joined in series and connected by a source of

W frequency \( \omega \). Power dissipated in the circuit is:
(1) \( \frac{\left(R^{2}+\omega^{2} L^{2}\right)}{V} \)
(2) \( \frac{V^{2} R}{\left(R^{2}+\omega^{2} L^{2}\right)} \)
(3) \( \frac{V}{\left(R^{2}+\omega^{2} L^{2}\right)} \)
(4) \( \frac{\sqrt{R^{2}+\omega^{2} L^{2}}}{V^{2}} \)
