2. (15 pts) The reason why high voltage in power grid is used to transmit electric power is that it can reduce power waste along the transmission lines known as transmission loss. Suppose that a power station delivers 1,000 kW of power at 10,000 V to a city through wires with total resistance 3.0 22. How much power can be saved if the same power is delivered at 50,000 V?
