Transformers - Engineering

Q1:

What is the coefficient of coupling for a transformer in which 4% of the total flux generated in the primary does not pass through the secondary?

A 0.4

B 4

C 9.6

D 0.96

ANS:D - 0.96

Co-efficient of coupling usually considered as 1 means 100%.

If 4% do not pass then 100%-4% = 96% = 0.96.
