154931 Two coils of self - inductances $2 \mathrm{mH}$ and $8 \mathrm{mH}$ are placed so close together that the effective flux in one coil is completely linked with the other. The mutual inductance between these coils is

154932 A varying current in a coil changes from $10 \mathrm{~A}$ to zero in $0.5 \mathrm{~s}$. If the average emf induced in the coil is $220 \mathrm{~V}$, the self- inductance of the coil is

154934 What is the self-inductance of a coil which produces $5 \mathrm{~V}$ when the current changes from 3 $A$ to $2 \mathrm{~A}$ in one millisecond?

154937 Two coils are wound on the same iron rod so that the flux generated by one passes through the other. The primary coil has $N_{p}$ turns in it and when a current $2 \mathrm{~A}$ flows through it the flux in it is $2.5 \times 10^{-4} \mathrm{~Wb}$. If the secondary coil has 12 turns the mutual inductance of the coils is (assume the secondary coil is in open circuit)
