In the circuit shown what is that maximum number of switch that must be closed to turn on all the light ?

The given figure shows a simple circuit containing four bulbs and five switches along with a battery. What is the minimum number of switches that must be closed to light at least one bulb?

In the circuit shown in figure the switch S is closed at t = 0. A long time after closing the switch

In the circuit as shown in figure the switch is closed at t = 0 . A long time after closing the switch

In the LR circuit shown, what is the variation of the current I as a function of time? The switch is closed at time t=0 sec.

In the circuit as shown in figure the switch is closed at t = 0 . At the instant of closing the switch

In the circuit shown above, when then switch S is closed,

Consider the circuit shown in figure, after switch S is closed. What amount of charge will flow through the switch?

In which of the following circuits is the current maximum just after the switch S is closed?
