100 MW of electrical power is delivered at 200 kV to adistribution center over a transmission line which consumers 10% ofthe total power developed by the generating station in heat losses.
a) What is the value of the voltage fed to the transmission line at the generator end?
b) How much power would be delivered to the same load if theresistance of the transmission line was halved but the generatorvoltage was unaltered?
