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

Consider an electrical circuit containing a two way switch S . Initially S is open and then T _ 1 is connected to T _ 2

Correct answer

Step-by-step solution

When ${T}_{1}$ and ${T}_{2}$ are connected, then the steady state current in the inductor $I = \dfrac{6}{6} = 1A$

When ${T}_{1}$ and ${T}_{3}$ are connected then current through inductor remains same. So potential difference across $3Ω$

$V = Ir = 1 \times 3 = 3$ $V$
