An air conditioner draws 19A at 220-V ac. The connecting cord is copper wire with a diameter of 1.291mm.

A) If the length of the cord (containing two wires) is 6.5m , how much power is dissipated in the wiring?

B) If no. 12 wire, with a diameter of 2.053 mm, was used instead, how much power would be dissipated?

C) Assuming that the air conditioner is run 11h per day, how much money per month (30 days) would be saved by using no. 12 wire? Assume that the cost of electricity is 12 cents per kWh.
