The output of generator is 440 V at 20 A. It is to be transmitted on a line with resistance of 0.60 Ohms. To?
what voltage must the generator output be stepped up with transformer in the power loss in transmission is not to exceed 0.010 % of the original power ?
power = 440 x 20 = 8800 watts
0.01% of that is 0.88 watts
Power in the line:
P = I²R
0.88 = I²0.60
I = √88/60 = 1.21 amps
to generate 8800 watts with a current of 1.21 amps,
8800 = 1.21V
V = 7266 volts
