Switch testing

If the capacitors are uncharged prior to the switch being closed, the amount of heat dissipated in resistors R_(1) and R_(2) after the switch is closed would be in the ratio of

In the circuit shown, battery, ammeter , and voltmeter are ideal and the switch S is initially closed as shown. When switch S is opened

The switch in figure is closed at time t = 0 . Find the current in the inductor and the current through the switch as functions of time thereafter.

In the circuit shown below, the switch is in position 1 for a long time. At some moment after that the switch is thrown in position 2. The quantity of heat generated in the resistance of 375 ohm after the switch is changes to position 2 is :

In the circuit shown in figure switch S can be shift to position A or position B. Current though resistance is say i_(1) when switch is in position. A and when switch is in position B, then

Consider the following sentence: Switch on the light. Is it a statement?

Switch off the following barrier methods are reusable ?

DNA parts which can switch their position are

The switch in figure Iis connected to position a for a long time interval. At t = 0 , the switch is thrown to position b. After this time , what are

Assertion In the figure, just after closing the switch the potential drop across inductor is maximum. Reason The rate of change of current just after closing the switch is maximum.
