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 3:37. when used with 120-v (rms) household service, the transformer draws an rms current of 205 ma.(a) find the rms output voltage of the transformer. v(b) find the power delivered to the cd player.

N2/N1 = 3/37V prms = 120VInput V rms = 250 mA = 0.250AA.    N2/N1 = V2/V1       V2 = N2/N1   x V1       V2 = 3/37 x 120         V2 =  9.72 VB  Power = VI                = 120 V x 0.250                = 30 W     What is a Step Down Transformer?A step-down transformer is a type of transformer that converts the high voltage (HV) and low current from the primary side of the transformer to the low voltage (LV) and high current value on the secondary side of the transformer. The reverse of this is known as a step up transformer.For reducing a high voltage AC For providing a high current at a lower voltage.For providing – for safety – isolation of your lower voltage ac supply from the mains power supply.To know more about Step down transformer from the given linkhttps://brainly.com/question/15200241#SPJ4
