Question:

In the single-phase power system of Fig. 1.1, the voltage and current are as follows:
\[
\begin{aligned}
v(t) & =110 \cos \left(\omega t+30^{\circ}ight) V \\
i(t) & =0.5 \cos \left(\omega t-30^{\circ}ight) A
\end{aligned}
\]
Determine the impedance, resistance, and reactance of the system seen from the beginning of the line.
1) \(\left(220 /-60^{\circ}ight) \Omega, 110 \Omega, 110 \sqrt{3} \Omega\)
2) \(\left(220 / 60^{\circ}ight) \Omega, 110 \Omega, 110 \sqrt{3} \Omega\)
3) \(\left(220 \angle-30^{\circ}ight) \Omega, 110 \sqrt{3} \Omega, 110 \Omega\)
4) \(\left(220 / 30^{\circ}ight) \Omega, 110 \sqrt{3} \Omega, 110 \Omega\)
