An AC generator supplies 15 amps at 440V to a 50,000V power line through a step-up transformer.
(a) what must the turn ratio in the transformer be to achieve this?
(b) If this electricity is transmitted for 100km with a resistance of .75 Ohms/km, how much money would the energy supplier save per month if electricity costs $0.12/kWh by stepping up the voltage. (assuming that the energy is supplied continuously)?
