Op-amp question

  1. Nov 13, 2013 #1
    Problem in paint doc.
    I'm interested in why V- = 0.

    Is it always true that V- = 0?
    If not how was it decided that V- = 0 for this given probem?

    Nevermind I figured it out. V+ = 0
    and V+ = V-

    You still asked a good question. Is V- always zero?
    Answer: no, but it's always = V+ unless the op amp output is saturated.
