Here we are given a 4 kilo ohm resistor which is connected to a 9 volt source of the current.
00:09
Then this circuit resistor is again in series of another 4 kilo ohm resistor.
00:15
Then a branch is reaching up from here that consists of a 8 kilo ohm resistor which is connected to a 2 kilo ohm resistor and the circuit from here is somewhat like this.
00:30
This branch from here is interconnected from the another branch of the circuit.
00:37
Let's say here this is the vs voltage source which after that is earthed.
00:46
So this circuit from here is connected in somewhat like this.
00:50
So here is the voltage source v0.
00:53
So from here we have to calculate the value of v0.
00:57
So to calculate this we are using kirchhoff's law or we can say that the kirchhoff's current law.
01:08
So from the kirchhoff's law in the circuit or we can say that at the first node i1 is equals to i2 plus i3.
01:19
So i1 from here is let's say i1.
01:24
This is i1 from here.
01:26
This is the value current i2 moving from here.
01:31
I3 is moving in this loop and i4 is moving here in this loop.
01:38
So from here we can say that i1 is equals to 9 minus v0 that is divided by 4 is equals to v of a minus v of b that is divided by 4 plus v of a minus v0 that is divided by 8.
01:54
So solving this term from here we get the equation that from here is somewhat like this that is 5 of v a minus 2 of v b is equals to v0 that from here is equals to 18.
02:06
Let's say this is the equation number 1.
02:09
So from here we can say that that the voltage at inverting and non -inverting terminal of an ideal ideal op amp meter are equal.
02:21
So from here we can say that vb is equals to vs that is given to us that is equals to 2 volt.
02:27
So from the equation 1 here we can say that that 5 of a minus 2 of v of s minus v0 is equals to 18.
02:38
So we can write here that 5 of a minus 2 and we are having the value of vs that is 2 minus v0 that is equals to 18.
02:47
So simplifying from here we get the another equation from here that is 5 of vc minus v0 is equals to 22...
