    Hello everyone,

    I have a quick questions and was wondering if anyone can offer some
    help. My problem is I have a circuit with an inverted op amp where one
    voltage (1V) is going into the negative input and another voltage (4V)
    is going into the positive input. On the output RL = 10K Ohms. I have
    to determine Vo, not Vout. Aol is equal to 100,000, Io(max) is equal
    to 25ma and Vout is equal to 12V. How would I figure out Vo?

    What node is Vo..? Or Vo is on what?

    Is the Vo that you are striving to understand the 'offset voltage' ?

    If so this is the voltage between the opamp inputs needed to set the
    output voltage to zero. (Of course this definition will make the mose
    sense on a layman level when the opamp is powered by bipolar +/-
    supplies.
