An ideal step-down transformer is used to convert the ac


An ideal step-down transformer is used to convert the AC voltage from the power line at 120V to 5.0V in an adapter for your laptop computer.

(a) The primary coil has 2000-turns, how many turns are in a secondary coil?

(b) If the average power consumption of your laptop is 80W, what is the average current in the primary coil and the current I in the secondary coil?

(c) What is the load resistance R in the secondary coil? Assume that it is an ideal transformer
