    If it is an electrolytic or tantalum (the type polarity matters) one end will be marked with a + or a -- sign. If there is no marking, the capacitor is non-polarized and it doesn't matter.

    10 microfarad may well be polarized

    there are several types

    don't put power to it until you are sure

    they can explode

    Use a voltmeter!!!!!

    anyone of the leads can be positive, depends on the volatge which was applied on it.

    For a non-electrolytic capacitor, there isn't any. If it is an electrolytic capacitor, the leads will be marked.:

    neither one

    put it either way, doesn't matter

    those tiny ones are usually used for clipping noise or creating timing pulses
