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 1:13. When used with 120 V (rms) household services, the transformer draws an rms current of 20.0 mA from the house outlet. Find (a) the rms output voltage of the transformer and (b) the power delivered to the DVD player.
