In the following RC circuit, key is kept closed for a long time and then it is opened at t=0. Wh...

The switch S shown in figure is kept closed for a long time and is then opened at t=0 .Find the current in the middle 10(Omega) resistor at t=1.0ms .

The switch S shown in figure is kept closed for a long time and then opened at t = 0, then the current in the middle 20 Omega resistor at t = 0.25 ms is :

In Fig. switch S is closed for a long time. At t = 0 , if it is opened, then

In given LR circuit the switch S is closed at time t=0 then
