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

Three coils of inductance $L_1 = 2 \ H$, $L_2 = 3 \ H$, and $L_3 = 6 \ H$ are connected such that they are separated from each other. To obtain an effective inductance of $1 \ H$, which of the following combinations, as shown in the figure, is correct?

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?

Two inductors of $80 \ mH$ each are joined in parallel. The current passing through the combination is $2.1 \ A$. The energy stored in this combination of inductors is

Two inductors of $60 mH$ each are joined in parallel. The current passing through this combination is $2.2 A$. The energy stored in this combination of inductors in joule is

Initially,the switch $S$ is open and the energy stored in the inductance $L$ connected in series with the battery is $E$. Now,the switch $S$ is closed. The energy stored in both the inductors after a long time is
