A transformer has two sets of coils, the primary with N1 = 190 turns and the secondary with N2 = 925 turns. The input rms voltage (over the primary coil) is ΔV1rms = 258 V. 1. Express the output rms voltage, ΔV2rms, in terms of N1, N2, and ΔV1rms.  2. Calculate the numerical value of ΔV2rms in V.

The primary coil of a transformer has N1 = 4.25 x 102 turns, and its secondary coil has N2 = 1.28 x 103 turns. If the input voltage across the primary coil is Av = (190 V) sin wt, what rms voltage is developed across the secondary coil? 572.23 Your response differs from the correct answer by more than 10%. Double check your calculations. V
