Hi, I was given a question to express Vload in terms of Rload, R and Vth. However, I am a bit confused as to what exactly is going on at Vout_a.
Assuming the op-amp is ideal, I first made statements regarding what voltages were equivalent.
Vload = Vout
Vout = Vn (negative terminal of op amp)
Vn = Vp (positive terminal of op amp)
Vp = Vout_a
The problem that I run into is figuring out what Vout_a is. I tried doing KCL at that node, but all i get is that Vout_a is equal to Vth since no current can pass through the input terminals of an op-amp. And that's where I'm stuck because a lot of things just don't seem to add up with my thought process
