Energy is to be transmitted over a pair of copper wires in a transmission line at the rate of 20.0 kW with only a 1.00% loss over a distance of 18.0 km at potential difference ΔVrms = 1.50 × 103 V between the wires. Assuming the current density is uniform in the conductors, what is the diameter required for each of the two wires?

Question

Energy is to be transmitted over a pair of copper wires in a transmission line at the rate of 20.0 kW with only a 1.00% loss over a distance of 18.0 km at potential difference ΔV_rms = 1.50 × 10³ V between the wires. Assuming the current density is uniform in the conductors, what is the diameter required for each of the two wires?
