Consider an electrical circuit containing a two way switch ' $\displaystyle S$ '. Initially $\displaystyle S$ is open and then $\displaystyle T_1$ is connected to $\displaystyle \mathrm{T}_2$. As the current in $\displaystyle \mathrm{R}=6 \Omega$ attains a maximum value of steady state level, $\displaystyle \mathrm{T}_1$ is disconnected from $\displaystyle \mathrm{T}_2$ and immediately connected to $\displaystyle \mathrm{T}_3$. Potential drop across $\displaystyle \mathrm{r}=3 \Omega$ resistor immediately after $\displaystyle \mathrm{T}_1$ is connected to $\displaystyle \mathrm{T}_3$ is \_\_\_\_ V.
