Social ScienceAn electric power station that operates at 15 kV and uses a 20:1 step-up ideal transformer is producing 370 MW (Mega-Watt) of power that is to be sent to a big city which is located 240 km away with only 2.5% loss. Each of the two wires are made of copper (resistivity = 1.68×10−81.68×10−8 Ω.m). What is the diameter of the wires?
