Hello students, we have a circuit of capacitors.
00:05
So this is a circuit.
00:07
This is capacitor c1 and this is v1 and a resistor here.
00:14
Here it is connected.
00:17
We have c2 here and this is 20 kilo ohm.
00:23
Right.
00:23
This is 30 kilo ohm.
00:26
Here we have a 5 and this is a voltage source 15 volts.
00:32
This is 5 kilo ohm and this is 15 kilo ohm.
00:42
This is c4.
00:43
This is 10 kilo ohm and we have a capacitor here as well c3.
00:57
So we need to find out this is v1.
01:00
We need to find out v2.
01:01
We need to find out v3 here.
01:04
V3 we need to find out and v4 we need to find out.
01:08
This is the source right from the source.
01:11
So in between the source for this capacitor, let's take v1.
01:16
So the connection goes like this.
01:18
So it goes through this like this.
01:20
So we have a series connection of 25 kilo ohms here.
01:26
So the resistance across the capacitor.
01:30
So v of the capacitor right v of the capacitor or v1 will be calculated as v of the source times zc by zt.
01:41
So zc is equal to 1 by j omega c.
01:47
So here it will be so we can substitute the value.
01:53
So v1 will be equal to v source is equal to 15 times zc is 1 by j omega c1 times zt.
02:04
Zt is the series connection of this thing.
02:07
So that is 20 plus 5 that is 25.
02:11
So that is equal to 3 by sorry 5 by or or you can say 3 by 5 3 by 5 j omega c1 is the voltage 1 3 by 5 j omega c1 is the voltage 1.
02:31
Okay now voltage 2.
02:35
So let's find out voltage 2 with the same equation.
02:37
So we have 15 and we need to find out zc is equal to 1 by j omega c2 and we need to find out what the zc we got it.
02:48
But what about z total so impedance total impedance will be the the total resistance through.
02:55
So this is 30 kilo ohms and 5 kilo ohms in series in parallel.
03:00
So the r effective will be equal to 1 by 30 plus 1 by 5 that is 5 plus 30 by 150...
