A 440-Vrms source supplies power to a load<br />
Z L = 10 + j2Ω <strong>th</strong>rough a transmission line<br />
having a total resistance of 1.5Ω. Find (a) <strong>th</strong>e<br />
average and apparent power supplied to <strong>th</strong>e<br />
load; (b) <strong>th</strong>e average and apparent power lost in<br />
<strong>th</strong>e transmission line; (c) <strong>th</strong>e average and<br />
apparent power supplied by <strong>th</strong>e source; (d) <strong>th</strong>e<br />
power f<strong>ac</strong>tor at which <strong>th</strong>e source operates.
