The inductance between $A$ and $D$ is

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

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 .......... $H$.

The equivalent inductance between $A$ and $B$ is equal to

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?

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 $H$)
