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

Two inductors $L_1$ and $L_2$ are connected in parallel,and a time-varying current flows as shown. The ratio of currents $i_1/i_2$ at any time $t$ is:

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

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 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 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 $H$)
