An air conditioner draws 13 A at 220V ac. The connecting cord is copper wire with a diameter of 1.528mm.

a) If the total length of the wire is 17 how much power is dissipated in the writing?

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 11 hr 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.
