A high-voltage transmission line carries 500 A at 700 kV for a distance of 100 miles.If the resistance in the wire is 1 Ω/mile,what is the power loss due to resistive losses?

Question

Quizplus · Accepted Answer

Power loss due to resistive losses is given by:

P = I^2 * R * L

where, 
I = current = 500 A 
R = resistance = 1 Ω/mile 
L = distance = 100 miles

Substituting the values, we get:

P = (500)^2 * 1 * 100 = 25,000,000 W = 25 MW

Therefore, the correct answer is option C.

A High-Voltage Transmission Line Carries 500 a at 700 KV
