    In the photo below, the top two cap's negative lead is on the right.
    (The "-" sign is pointed towards the right.)

    The next three appear to be non-polarized.

    Here, again, the negative lead is indicated by the arrows.

    a polarized electrolytic cap will have the (-) side marked on one side with an arrow pointing to the (-) lead, a non polarized electrolytic will not matter how it is hooked up there is no (-) or (+) side.


    These are polarized electrolytic caps....
