9.6 Exercise 3

Avg difficulty 2.5

Consider a power plant is located 60 km away from a residential area uses 0-gauge (A=42.40mm2)\left(A = 42.40 \text{mm}^{2}\right) wire of copper to transmit power at a current of I=100.00AI = 100.00 \text{A}. How much more power is dissipated in the copper wires than it would be in superconducting wires?
