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
