154777 A graph of magnetic flux $(\Phi)$ versus current (I) is shown for four inductors $A, B, C$ and $D$. Larger value of self-inductance is for inductor

154778 A circular coil consists 70 closely wound turns and has a radius of $10 \mathrm{~cm}$. An externally produced magnetic field of magnitude $2 \times 10^{-3} \mathrm{~T}$ is applied perpendicular to the coil. The net flux through the coil is found to vanish when the current in the coil is $2.2 \mathrm{~A}$. The inductance of the coil is

154781 Two coils have a mutual inductance of $0.01 \mathrm{H}$. The current in the first coil changes according to equation $I=5 \sin 200 \pi t$. The maximum value of e.m.f. induced in the second coil is

154782 The magnetic flux through a coil is $4 \times 10^{-4}$ $\mathrm{Wb} / \mathrm{m}^{2}$ at time $\mathrm{t}=0$. It reduces to $10 \%$ of its original value in $t$ seconds. If the induced e.m.f. is $0.72 \mathrm{mV}$, then the time $t$ is

154783 A pair of coil has a mutual inductance of $2 \mathrm{H}$, if the current in the primary changes from $10 \mathrm{~A}$ to zero in $0.1 \mathrm{~s}$, the induced emf in the secondary will be
