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 = 6Omega` 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 = 3Omega` resistor immediately after `T_(1)` is connected to `T_(3)` is______V. (Round off to the Nearest Integer)
