A transformer is to be used to provide power for a computer disk drive that needs 5.0 V (rms) instead of the 120 V (rms) from the wall outlet. The number of turns in the primary is 415, and it delivers 500 mA (the secondary current) at an output voltage of 5.0 V (rms). (b) Find the current in the primary. mA (c) Find the number of turns in the secondary. turns
