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

 Pushpa said: (Dec 21, 2010) IF U CONSIDER TOTAL FLUX IS 100% THEN HERE GIVEN 4% SO TOTAL FLUX=100%-4%=96%=0.96

 Bitan said: (Aug 4, 2011) Leakage flux is 4 % of the total flux, thus flux linked with the secondary is 96% of the total primary flux. Thus the co-eficient of coupling is 0.96.

 Sulthana said: (Jul 16, 2013) Yes it is right if we consider that total flux is 100% where leakage flux is 4%of total flux. Then total flux-leakage flux (100-4) =96%=0.96.

 R. Parthiban said: (Aug 2, 2013) K = I1/I2 and Flux1/Flux2. So K = 4 / 100. K = 0.96.

 Bimal said: (Oct 14, 2013) Total flux is 100% and 4% does not pass means left is 96% or 0.96.

 Albert said: (Feb 12, 2014) Total flux is 100% & 4 % is given, So 4/100 = 0.96.

 Basavaraj said: (Mar 18, 2019) Yes, you are right @Bitan.

 Haris said: (Jan 3, 2020) Co-efficient of coupling usually considered as 1 means 100%. If 4% do not pass then 100%-4% = 96% = 0.96.
