... 39. (II) A power station delivers 620 kW of power at 12,000 V to a factory through wires with total resistance 3.0 . How much less power is wasted if the electricity is delivered at 50,000 V rather than 12,000 V? Solution Find the current used to deliver the power in each case, and then find the po ...
