If the current 30A flowing in the primary coil is made zero in 0.1 sec, the emf induced in the secondary coil is 1.5 volt. The mutual inductance between the coils is

0.05 H

1.05 H

0.1 H

0.2 H

Solution

0.05 H

When the emf is induced in a single isolate coil due to change of flux through the coil by means of varying the current through the same coil, this phenomenon is called self-induction & mutual induction as the current flowing in one coil that induces in an adjacent coil.

here :- e= 1.5 volt ,Δi =0-3=-3A, Δt=0.1 sec

Now the emf induced in secondary coil

$e = \frac{M ∆ i}{∆ t} (numerically) \Rightarrow 1.5 = \frac{M \times 3}{0.1} \Rightarrow M = \frac{1.5 \times 0.1}{3} = 0.05 H$
