Three inductances are connected as shown in the figure. The equivalent inductance is

Two identical inductors, each of inductance $L$, are connected in two different configurations $P$ and $Q$, through which a time-varying current $I(t)$ flows. The induced emf between points $a$ and $b$ for configuration $P$ is $E_P$ and that for configuration $Q$ is $E_Q$. The ratio $E_P/E_Q$ is: [Neglect the effect of mutual inductance.]

The equivalent inductance of two inductances is $2.4 \, H$ when connected in parallel and $10 \, H$ when connected in series. The difference between the two inductances is .......... $H$.

In the given circuit, the current through the $5 \, mH$ inductor in steady state is

Three inductances are connected as shown in the figure. The equivalent inductance between $A$ and $B$ is (in $H$)

An inductor coil of inductance $L$ is cut into two equal parts and both the parts are connected in parallel. The net inductance is
