What Is the Nodal Voltage Vb When a 1k Resistor Is Shorted in an Op-Amp Circuit?

Click For Summary
SUMMARY

The discussion centers on determining the nodal voltage Vb in an operational amplifier (op-amp) circuit when a 1kΩ resistor is shorted. The user initially calculates Vb to be 90.1mV with the resistor in place. However, the clarity of the provided circuit image is questioned, as it hinders accurate analysis. The thread was also redirected to the Homework Help forum for appropriate categorization.

Hi I was just wondering what the nodal voltage Vb would be if you shorted the 1k resistor shown in this pic: http://img401.imageshack.us/my.php?image=opampem4.jpg

also with that resistor in place what would the nodal voltage Vb be? i get 90.1mV

ty in advance

Couple problems. First, this should be posted in the Homework Help forums, not in the general EE forum. Homework and coursework belong in Homework Help, where I'm moving the thread now, leaving a redirect behind.

Second, the image at imageshack is not clear, at least not to me on my home laptop with IE.

Third, that imageshack URL results in multiple pop-ups with music and all kinds of garbage invading my laptop. Please upload a cleaner drawing to this thread, so we can help you out.
