    Opamp (operational amplifier)
    could be a Voltage Source (usually there is a symbol in the circle)
    Constant Current Source

    Why did you post this under "mathematics"? I would think it would do better under "Physics".

    the first one looks like a comparator, not an opamp.

    opamps can be comparators...

    its been a while since i went thru opamps. but as far as i remember, opamps are made up of comparators.

    Comparators as well as inverting amps, non-inverting amps, summers, differentiators, and integrators, etc are made up of op-amps. A comparator is an application of an op-amp.
