An electric generator rated 12 kW, 2 kV distribute power through a cable of resistance 20(Omega). Calculate the power loss in the cable.

  • A.
    120 w
  • B.
    360 w
  • C.
    720 w
  • D.
    2400 w
Correct Answer: Option C
Explanation

Power – IV
I = (frac{P}{V})
= (frac{12000}{2000})
I = 6A
Power loss = I(^2)R = 6(^2) x 20
= 720 W
