A transformer is to be used to provide powerfor a computer disk drive that needs 6.4 V (rms) instead of the 120V (rms) from the wall outlet. The number of turns in the primary is410, and it delivers 500 mA (the secondary current) at an outputvoltage of 6.4 V (rms).

(a) Find the current in the primary.

_____________ mA

(b) Find the number of turns in the secondary.

_____________ turns
