Transformation ratio is Zsec = a(square) x Zpri

whereas, turn ratio is Ns/Np = Vs/Vp = Ip/Is

Answer / 7anoter4

The transformation ratio of a power transformer it is the ratio between primary
EMF [Electric Magnetic Force-the voltage induced by magnetic flow in a coil] and secondary EMF.This ratio equals the ratio between primary and secondary number of turns.

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?
