Answer to Question #91119 in Electric Circuits for Ali

Question

Quebec Francious Power is producing 11 120 MW of electrical energy right now. If they were attempting to transmit this power through a 2.0 ohms line using a potential difference of 75.0 MV, what would be the % power loss in the line?

Answer 1

The % power loss in the line:

$$\frac{P_{loss}}{P}100\%=\frac{RP}{U^2}100\%=\frac{2(11120000000)}{75000000^2}100\%=0.0004\%$$
