The rechargable battries for a labtop computer needs a smaller voltage than what a wall socket provides. Therefore a transformer is pluged into the wall socket and produces the necessary voltage for changing the batteries. The batteries are rated at 9.0 V, and a current of 225 mA is used to charge them, The wall socket provides a voltage of 120 V. (a) Determine the turns ratio of the transformer. (b) What is the current comming from the wall socket? (c) Find the avaerage power delivered by the wall socket and the average power sent by the batteries.
