7. An electric power station that operates at 25 kV and uses a 10:1 step-up ideal transformer is producing 36 MW (Mega- Watt) of power that is to be sent to a big city which is located 270 km away with only 1.5% loss. Each of the two wires are made of copper (resistivity = 1.72 × 10−8 2.m). What is the diameter of the wires? cm
