A step-down transformer is used for recharging the batteries of portable devices. The turns ratio N2/N1 for a particular transformer used in a CD player is 7:72. When used with 120 V (rms) household service, the transformer draws an rms current of 250 mA. Find the following.
(a) rms output voltage of the transformer?
=____ V
(b) power delivered to the CD player?
=_____ W
