An a.c. source given by $$V=V_m\sin\omega t$$ is connected to a pure inductor $$L$$ in a circuit and $$I_m$$ is the peak value of the AC current. The instantaneous power supplied to the inductor is:
1.  $$\frac{V_mI_m}{2}\mathrm{sin}(2\omega t)$$
2.  $$-\frac{V_mI_m}{2}\mathrm{sin}(2\omega t)$$
3.  $${V_mI_m}\mathrm{sin}^{2}(\omega t)$$
4.  $$-{V_mI_m}\mathrm{sin}^{2}(\omega t)$$

An AC voltage source is connected to a series $$LCR$$ circuit. When $$L$$ is removed from the circuit, the phase difference between current and voltage is $$\frac{\pi}{3}$$. If $$C$$ is instead removed from the circuit, the phase difference is again $$\frac{\pi}{3}$$ between current and voltage. The power factor of the circuit is:
1. $$0.5$$
2. $$1.0$$
3. $$-1.0$$
4. zero
