Question

derivation of transformer ratio​

Answer 1

Explanation:

The rate of change of flux with respect to time is derived mathematically. As shown in the above figure that the flux changes from + ϕm to – ϕm in half a cycle of 1/2f seconds. So the induced emf lags flux by 90 degrees. The above equation is called the turn ratio where K is known as the transformation ratio.
