Question

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 $R = 6 Ω$ attains a maximum value of steady state level, $T_{1}$ is disconnected from $T_{2}$ and immediately connected to $T_{3}$ . Potential drop across $r = 3 Ω$ resistor immediately after $T_{1}$ is connected to $T_{3}$ is _____ $V$ .
(Round off to the Nearest Integer)

Open in App

Solution

When $T_{1}$ and $T_{2}$ are connected, then the steady state current in the inductor will be,

$I = \frac{6}{6} = 1 A$

When $T_{1}$ and $T_{3}$ are connected then current through inductor remains same. So potential difference across $3 Ω$ resistor is,

$V = I r = 1 \times 3 = 3 volt$

When T1 and T2 are connected, then the steady state current in the inductor will be, I=66=1 A When T1 and T3 are connected then current through inductor remains same. So potential difference across 3Ω resistor is, V=Ir=1×3=3 volt

When $T_{1}$ and $T_{2}$ are connected, then the steady state current in the inductor will be,
