Please explain clearly relation among coefficient of coupling, voltage, turns ratio.

Voltage induce in a transformer = (coeff. of coupling)*(ideal v).
Normally we take coefficient of coupling as 1.
But here it is mentioned as 0.85.
= 0.85*2.
= 1.7.

The COEFFICIENT OF COUPLING(M) of a transformer is dependent on the portion of the total flux lines that cuts both primary(L1) and secondary(L2) windings.

Voltage induced =coefficent of coupling*voltage caliculated
if itwas not given we will simply take it as 1
v2/v1=n2/n1=1
v2=v1=2
Voltage induced = 2*.85 = 1.7v
if itwas not given we will simply take it as 1
v2/v1=n2/n1=1
v2=v1=2
Voltage induced = 2*.85 = 1.7v
