If the switch is closed for long time and then open at `t = 0`, the P.D across indicator at `t = 0` is

The switch is closed for a long time and then opened at time t = 0. Find the initial voltage across L after t = 0, which end is at higher potential P or Q?

The switch is closed for a long time and then opened at time t = 0. Find the initial voltage across L after t = 0, which end is at higher potential P or Q?

The switch is closed for a long time and then opned at time t=0 . Find the initial voltage across L after t=o , which end is at higher potential a or b ?

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

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

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 10Omega resistor at t=1.0ms
