The primary winding of the transformer is connected to a network with a voltage of 480 V. What is the value of the EMF

The primary winding of the transformer is connected to a network with a voltage of 480 V. What is the value of the EMF that occurs in the secondary winding if the primary winding contains 1500 turns of wire, and the secondary contains 100 turns?

First, we need to find the transformation ratio. It can be found according to the formula k = N1 / N2, where N1 is the number of turns in the first winding, and N2, respectively, in the second. So k = 1500/100 = 15.
EMF = U1 / k, where U1 = 480 V.
EMF = 480/15 = 32 V.
Answer: 32 V.
