Hello,
I am asked to find the dependent voltage source of the following and choose the right polarity. (see attached file)
I know the dependent source is A0Vin , so I have to do KVL for it. My current is clockwise for each loop
From figure 3:
KVL1: IA0Vin + IRL = 0
and I know, I = V0/RL
Therefore KVL1: (V0A0Vin)/RL + V0 = 0
Then I did a KVL for the left circuit.
KVL2: -Vs + I2Ra + I2Rb = 0
Also I2=Vx/Rb
Therefore KVL2: -Vs + VxRa/Rb + Vx = 0
And that's as far as I got so far.
From the diagram it looks like the 2 loops in Figure 3 do not connect, also there is no feedback of the op amp in the diagram. So i'm confused how to relate.
I'm wondering if in KVL1 if Vin = Vs
But I'm not sure.
