Hello, in the question we have to calculate the output voltage for the circuit.
00:06
So we have given this circuit, so we have to calculate the output voltage over here.
00:11
So here we have this configuration.
00:14
Now this non -inverting terminal, it is grounded.
00:20
So according to the virtual ground concept, so this will be equal to zero.
00:25
So we are calling this va.
00:27
So this potential will be equal to zero.
00:30
So here we will just write this.
00:33
So let us mention this.
00:35
So va will be equal to zero by the concept of virtual ground.
00:40
So by the concept of virtual ground, so this is equal to zero.
00:48
Now over here, what can we do over here is, so now this is virtually grounded.
00:57
So this is at potential zero.
00:59
So if this point is at zero, this point should be zero.
01:02
So now suppose there is current coming from this.
01:05
So let us say from here, the current coming is i1, from here the current coming is i2 and then this will meet, these two currents will meet at a junction and then from here it will go over here, that is i0...
