Question

A transmission line having a total resistance of 0.2Ω delivers 10kW at 220V to a small factory. Calculate the power loss in the line.​

Answer 1

Answer:

413.14

Explanation:

Power received by the factory or power output, Po = 10 kW = 104 W

Let I be the current received by the factory. VI = Po

=> I = Po/V = 104/220

= 45.45 A

Power lost as heat due Joule heating is, P/ = I2R = 45.452 × 0.2 = 413.14
