Question

it is 3 parts:: 1-- An ideal step-down transformer has a primary coil of 400 turnsand
a secondary coil of 27 turns. It is plugged into an outlet with
120 V (AC) from which it draws a current of
0.59 A.
What is the voltage in the secondary coil? 2--- Calculate the rms current in the secondary coil.
3--- Assuming that the transformer secondary is driving a resistiveload, calculate the average power dissipated in theresistor.

Explanation / Answer

given that       N1 = 400turns     N2 = 27turns    V1 = 120v    Ip = 0.59A    V1/ V2 = N1/N2 A)    V2 = V1N2/ N1 = 120*27/400 = 8.1v B) Is = Ip * N1/N2    = 0.59 * 400/27 = 8.7A   C) power out put =   V2Is = 8.1v* 8.7A = 70.8W
