All right.
00:01
So in this problem for the circuit shown below, the switch has been in a position a for a long time.
00:10
Capacitor is fully charged, right? at t equals to zero, the switch instantaneously moves to position b, right? find vc and 2 for t greater than 0 as a function of time.
00:32
All right? so now this is a.
00:35
The circuit given to us.
00:37
So here r1, r2, c1 is given to us and this is the switch a and v terminals are given to us, right? so now what happens is at steady state t equals to 0.
00:52
What happens is voltage between capacitors positive and negative ends remain same, right? so before switch changes, right, vc 0 will be equals to 10 volts, right? okay.
01:19
So now when switch moves to b, the circuit is closed without any power sources, right? circuit becomes rc, that is pure rc circuit.
01:31
So, what happens is what is vct? vct is given by vc0, that is vc not, you can say, multiplied...
