We want to find the voltage in each capacitor.
00:05
We know we have reached a steady state situation.
00:08
That means that there is no current in either of the branches that has a capacitor in it.
00:16
We can redraw the circuit like this.
00:21
The equivalent is 3 times 6 over 3 plus 6 which comes out to be 18 over 9 which is 2k ohms.
01:00
So we get a circuit that looks like this.
01:14
That means that the voltage across here is the current times the resistance which is 6 milliamps times 2k ohms which comes out to be 12 volts.
01:37
That means if i go backwards that this voltage across the 3k resistor is 12 volts.
01:50
So if i say let's call this point down here zero this one is going to be 12.
01:59
In this version that one is 12.
02:08
So here is our zero down here.
02:23
This point here is 8 because that is a voltage divider.
02:32
We know how that works.
02:34
That means that this point here is 8 which means this one is 8.
02:41
So there is no current here.
02:50
So that means the following.
02:54
The 8 microfarad capacitor has 8 volts across it...
