List of top Physics Questions on Inductance asked in AP EAPCET

An inductor of inductance \[ 5\,\text{H} \] is carrying an electric current of \[ 4\,\text{mA}. \] Then the energy stored in the inductor is

The ratio of the turns per unit length in two inductors is \[ 2:1. \] Then the ratio of the impedances produced by the inductors is

The coefficient of mutual induction between the primary and secondary coil of a transformer is $0.4\text{ H}$. When the current in the primary coil changes at the rate of $10\text{ As}^{-1}$, then the induced emf in the secondary will be:

The mutual inductance of a pair of adjacent coils is 5 H. If the current in one coil changes from 0 to 12 A in a time of 0.75 s, then the change of flux linkage with the other coil is:
