The rechargeable batteries for a laptop computer need a much smaller voltage than what a wall socket provides. Therefore, a transformer is plugged into the wall socket and produces the necessary voltage for charging the batteries. The batteries are rated at 9.0 V, and a current of 264 mA is used to charge them. The wall socket provides a voltage of 120 V. (a) Determine the turns ratio of the transformer. NsNp = 1 (b) What is the current coming from the wall socket? Ip = 2 3 ---Select--- V W C Ohm A (c) Find the average power delivered by the wall socket and the average power sent to the batteries. Pp = 4 5 ---Select--- C A Ohm W V Ps = 6
