In the single-phase power bus of Fig. 1.12, the characteristics of the loads are as follows. Determine the total power factor of the bus:

\[
\begin{gathered}
\text { Load } 1: P_{1}=25 k W, Q_{1}=25 k V A r \\
\text { Load } 2: S_{2}=15 k V A, \cos \left(\theta_{2}ight)=0.8 \text { Leading } \\
\text { Load } 3: P_{3}=11 k W, \cos \left(\theta_{3}ight)=1
\end{gathered}
\]

1) 0.94 Lagging 

2) 0.94 Leading 

3) 0.6 Lagging 

4) 0.6 Leading
