Determine the real power, $P$, the reactive power,$Q$, the complex power, $\textbf{S}$, and the power factor, $pf$, for three loads having the following characteristics.
Ref: Hayt, Sect. 11.5
$\textbf{I} = 2.5 \angle 205^{\circ} A_{rms}$
$\textbf{V} = 4 \angle 255^{\circ} V_{rms}$

$P =$ $W$

$Q =$ $VAR$

$\textbf{S} =$ $VA$

$pf =$
$\textbf{I} = 10 \angle 190^{\circ} A_{rms}$
$\textbf{Z} = 2900 \angle 40^{\circ} \Omega$

$P =$ $W$

$Q =$ $VAR$

$\textbf{S} =$ $VA$

$pf =$
$\textbf{V} = 9 \angle 210^{\circ} V_{rms}$
$\textbf{Z} = 4600 \angle 40^{\circ} \Omega$

$P =$ $W$

$Q =$ $VAR$

$\textbf{S} =$ $VA$

$pf =$
