Question

A 25 KW dc generator produces a P.d of 250 volt. If the resistance of the
transmission line is 10 ohm , what percentage of the original power is lost during the transmission
a) 40%
b) 50%
c) 25%
(correct answer is 25% how?)​

Answer 1

Answer:

Current= power/ voltage i= 25000/250 = 100 ampere power loss= I^2. R= 100X100X 1= 10000 WATT. % LOSS= 10000/25000= 40%.Aug 18, 2017
