A 300-km power line transmits 300 amps at 333,000 V source voltage. The transmission efficiency (the fraction of source power that reaches the destination) is 0.96. Perform your calculations as though the power line were operating with direct current; the calculation with alternating current requires the use of ac impedance rather than resistance.
