A power station delivers 513kW of power to a factory through wires of total resistance of 2.72Ohm. How much less power is wasted if the electricity is delivered at 45200V rather than 13900V?
I have no idea where to even begin except that I should find the intial current which is found by equation P=I^2R
Please help me!
