I do not think that this solution is for this question. Thesolution does not have anything to do or share any of the samevalues for the question in the book.
The book asks:
A GENERATOR SUPPLIES AN AVG POWER OF 12MW through atransmission line that has a resistance of 10ohm. What is the powerloss in the transmission line if the rms line voltage Erms is (a)15kv and (b) 110KV. What percentage of the total power supplies bythe generator is lost in the transmission line in each case?
