Atransformer has two sets of coils, the primary with n1 = 160 turns and the secondary with n2 = 1400 turns. the input rms voltage (over the primary coil) is δv1rms = 62 v. n1 = 160n2 = 1400δ v1rms = 62 v
1. express the output rms voltage, δv2 rms, in terms of n1, n2, and δv1 rms.2. calculate the numerical value of δv2rms in volts.

To solve the problem it is necessary to apply the concepts related to the voltage in a coil, through the percentage relationship that exists between the voltage and the number of turns it has.

So things our data are given by

PART A) Since it is a system in equilibrium the relationship between the two transformers would be given by

So the voltage for transformer 2 would be given by,

PART B) To express the number value we proceed to replace with the previously given values, that is to say
