A three$-$phase ungrounded voltage source is shown in Figure $4\mathrm{.}17.$ It is connected to

an unbalanced wye$-$connected load as shown. Assume the source is a balanced,

$120$ V $,$ line $^(-)$neutral $(208$ V $,$ line $^(-$l$)$ line$)$ sine wave voltage source.

Find the voltage between the neutral of the voltage source and the center point of

the unbalanced load.
