Initially, the switch is in position 1 for a long time. At `t = 0`, the switch is moved from 1 to 2. Obtain expressions for `V_C` and `V_R` for `tgt0`

Initially, the switch is in position 1 for a long time. At t = 0 , the switch is Obtain expressions for V_C and V_R for tgt0

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

In the circuit shown, initially the switch is in position 1 for a long time. Then the switch is shifted to position 2 for a long time. Find the total heat produced in R_(2)

In the circuit shown in the figure initialy the switch in position 1 for a long time, then suddenly at t=0 the switch is shifted to position 2. It is required that a constant current should flow in the circuit, the value of resistance R in the circuit

In figure, the switch is in the position 1 for long time, then the switch is shifted to position 2 at t=0 . At this instant the value of i_1 and i_2 are

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, the switch has been in position 1 for a long time. Now the switch is shifted to position 2. If this instant is taken as t = 0, then at time t=(pi)/(2)

Initially the switch is in positions 1 for as long time then shifted to position 2 at t=0 as shown in figure. Just after closing the switch, the magnitude of current through the capacitor is
