A step-down transformer is used for recharging the batteries of portable electronic devices. The turns ratio N2/N1 for a particular transformer used in a DVD player is 1:15. When used with 120-V (rms) household service, the transformer draws an rms current of 42.0 mA from the house outlet.
(a) Find the rms output voltage of the transformer
__________V
(b) Find the power delivered to the DVD player.
__________W
