Question:

A small city requires about 10 MW of power. Suppose that instead of suing high-voltage lines to supply the power, the power is delivered at 120V. Assuming a two wire line of 0.50-cm-diamter copper wire, estimate the cost of the energy lost to heat per hour per meter. Assume the cost of electricity is about 10 cents per kWh.
