1.two coupled coils with L1=L2=0.6 H have a coupling
coefficient of k=0.8 the turns ratio N1/N2 is......
Answer Posted / vinova
well frnd it cant be calculated as you can calculate mutual
inductance M = K*underoot(L1*L2)
Further M=(N1*N2)/S (s is reluctance)so the data in the
above question is insufficent to calculate N1 and N2. if it
is asssumed that both have same length l and both carry
same current and both have equal magnatic field intensity H
then it can be said that N1 and N2 are equal as H*l = N*I
here l s the length of conductor
