The pure inductors,each of inductance $6 \ H$,are connected as shown in the figure. Their equivalent inductance between the points $P$ and $Q$ is (in $H$)

Two inductors $A$ and $B$ when connected in parallel are equivalent to a single inductor of inductance $1.5 \ H$,and when connected in series are equivalent to a single inductor of inductance $8 \ H$. Find the difference in the inductances of $A$ and $B$. (in $H$)

In the given circuit below, the inductance values of $L_1$, $L_2$, and $L_3$ are the same. The magnetic energy stored in the entire circuit is $U_t$ and that stored in the $L_2$ inductor is $U_l$. The ratio $U_t/U_l$ is . . . . . . . (Ignore the mutual inductance, if any.)

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

The equivalent inductance of two inductors is $2.4 \, H$ when connected in parallel and $10 \, H$ when connected in series. What is the value of the inductances of the individual inductors?

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