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

AI Thread Summary
The discussion focuses on determining the nodal voltage Vb in an op-amp circuit when a 1k resistor is shorted, with one user suggesting a voltage of 90.1mV when the resistor is in place. However, the thread has been redirected to the Homework Help forum for appropriate categorization. Additionally, the provided image link is criticized for being unclear and problematic, with pop-ups affecting user experience. Participants are encouraged to upload a clearer diagram for better assistance. Clear communication and proper forum etiquette are emphasized for effective problem-solving.

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.
