A power plant produces 1000MW to supply a city 40km away. Current flows from the power plant on a single wire with resistance through the city and returns via the ground, with negligible resistance. At the power plant the voltage between wire and ground is 115 kV. Determine: (a) the current in the wire, and (b) the fraction of the power lost in transmission.
