Question:
(a) What current is needed to transmit 100 MW of power at 200 kV?
(b) What is the power dissipated by the transmission lines if they have a resistance of 1.00 Ω?
(c) What percentage of the power is lost in the transmission lines?
Strategy
We are given Pave = 100 MW, Vrms = 200 kV, and the resistance of the lines is R = 1.00Ω. Using these givens, we can find the current flowing (from P = IV) and then the power dissipated in the lines (P = I2 R), and we take the ratio to the total power transmitted.
