This is is an op-amp circuit from my text book that I'm not able to solve, please bear with my crappy ms paint skills please.
Sorry about the image size, dont know how to get it smaller... Anyway,
this is kinda like a basic inverting op-amp circuit, EXCEPT about the R4 in the middle,which makes it kinda confusing for me
Now the question stats this : Find VO when R1 = 80 kΩ; R2 = 50 kΩ; R3 = 70 kΩ; R4 = 30 kΩ and Vin = 5 V
What I did so far is:
( (Vi-Vx)/R1 + (Vo-Vi)/R3 + Vy/R4 + (Vy-Vx)/R2 )= 0
Where Vx = node on the left and Vy = node in the middle.
Now obviously I can't solve this question with my equation, this is where you guys come in.
Thanks in advanced.
