So, here in this question we have a circuit.
00:02
Now, switch is, was open, okay, switch was open for, okay, for plus c.
00:18
So, for this t is equal to zero minus, which is steady state, that vc is zero, minus will be equal to 12 minus 2 multiplied by 3, that's equal to 6 voltage.
00:34
Now, for t infinity, what's happening here? switch is closed and for t greater than zero and steady state at t infinity, okay, that react, that particular equation will come out as, we will write one by one, okay, that is vc of infinity that's equal to 12 volt.
00:56
After getting this, okay, we will have the t greater than zero, this is for t infinity, for t greater than zero, okay, t greater than zero, the vc of t is equal to vc of infinity minus of vc infinity plus, i mean, minus vc zero, okay, e to the power minus t divided by tau, okay...
