    Hi every body...

    I'm really confused about applying kvl on op amps....I really don't know how to detect loops of KVLs. I'm guessing that there is a more precisest definition of KVL with op amps.

    Simply I don't where to start a loop & where to close it.

    My quiz is tomorrow!!!

    I suppose, you speak about opamps with feedback, correct?
    Thus, you have a feedback loop - and you have two voltage sources feeding this loop:
    The input signal voltage and the opamp output voltage (which can be treated as a voltage source due to the low output impedance).
