Three identical resistors with resistance $R = 12\,\Omega$ and two identical inductors with self-inductance $L = 5\,mH$ are connected to an ideal battery with an emf of $12\,V$ as shown in the figure. The current through the battery long after the switch has been closed will be $......A$.

Consider an electrical circuit containing a two-way switch $S$. Initially,$S$ is open and then $T_{1}$ is connected to $T_{2}$. As the current in $R = 6 \, \Omega$ attains a maximum value of steady-state level,$T_{1}$ is disconnected from $T_{2}$ and immediately connected to $T_{3}$. The potential drop across the $r = 3 \, \Omega$ resistor immediately after $T_{1}$ is connected to $T_{3}$ is $.... \, V$. (Round off to the nearest integer)

$A$ series $L-R$ circuit is connected to a battery of emf $V$. If the circuit is switched on at $t = 0$,then the time at which the energy stored in the inductor reaches $\left(\frac{1}{n}\right)$ times of its maximum value,is

In the circuit shown below,the key $K$ is closed at $t = 0$. The current through the battery is

An emf of $20\; V$ is applied at time $t=0$ to a circuit containing in series $10\; mH$ inductor and $5\; \Omega$ resistor. The ratio of the currents at time $t=\infty$ and at $t=40\; ms$ is close to: (Take $e^{2}=7.389$)

For the given circuit,the current through the battery of $6\,V$ just after closing the switch $S$ will be $.......A$.
