Question

Consider an electrical circuit containing a two way switch ' $S^{\prime }$. Initially $S$ is open and then $T_1$ is connected to $T_2$. As the current in $R=6\Omega$ attains amaximum value of steady state level, $T_1$ is disconnected from $T_2$ and immediately connected to $T_3$. Potential drop across $r=3\Omega$ resistorimmediately after $T_1$ is connected to $T_3$ is______ $V$.
(Round off to the Nearest Integer)

Answer 1

Answer: 3

When $T_1$ and $T_2$ are connected, then the steady state current in the inductor
$I=\frac{6}{6}=1A$
When $T_1$ and $T_3$ are connected then current through inductor remains same.
So potential difference across $3\Omega$
$V=Ir=1\times 3=3$ volt
