Figure 1.7 shows the single-line diagram of a power system with the following specifications. Calculate the resistance of the load in per unit (p.u.) if the nominal quantities of the generator are chosen as the base quantities:

\[
\mathrm{G}: 20 \mathrm{kV}, 300 \mathrm{MVA}
\]
\[
\begin{gathered}
\mathrm{T}_{1}: 20 / 200 k V, 375 M V A \\
\mathrm{~T}_{2}: 180 / 9 k V, 300 M W
\end{gathered}
\]
Load : \(9 k V, 180 M W\)

1) \(1.25 \mathrm{p} . \mathrm{u}\).

2) \(1.35 \mathrm{p} . \mathrm{u}\).

3) \(1.45 \mathrm{p} . \mathrm{u}\).

4) \(1.55 \mathrm{p} . \mathrm{u}\).
