An alternating current of frequency $200\,rad/sec$ and peak value $1\,A$ as shown in the figure, is applied to the primary of a transformer. If the coefficient of mutual induction between the primary and the secondary is $1.5\, H$, the voltage induced in the secondary will be.....$V$

The induction coil works on the principle of

The mutual inductance between the rectangular loop and the long straight wire as shown in figure is $M$.

The mutual inductance between a primary and secondary circuits is $0.5 \,H$. The resistances of the primary and the secondary circuits are $20\,\Omega$ and $5\,\Omega $ respectively. To generate a current of $0.4 \,A$ in the secondary, current in the primary must be changed at the rate of.....$A/s$

If a change in current of $0.01\, A$ in one coil produces a change in magnetic flux of $1.2 \times {10^{ - 2}}\,Wb$ in the other coil, then the mutual inductance of the two coils in henries is.....$H$

Two coil $A$ and $B$ have coefficient of mutual inductance $M = 2H$. The magnetic flux passing through coil $A$ changes by $4$ Weber in $10$ seconds due to the change in current in $B$. Then
