Default Extreme Newbie Question need help ?

I bought two 1000 uF radial capacitors from Radio-Shack yesterday. And I relized I have no clue about their polarity. I have a theory that the short lead is the negative terminal, but I'm not sure ? PS: they are made by JAMICO

Basically there are two sorts of capacitors: the polarised and the non-polarized caps.
Jean-Paul can dig you up a thousand more, be we talk basic here.
The upper one on the picture is a radial polarised cap. You can clearly see the -sign corresponding to the shortest lead.
Non-polarised caps often have the inscription BP that means bipolar. The lower cap is an axial bipolar type.
The BP-types donít care about polarity as the name says.
With the polarised types you get a nice bang when applying wrong polarity.
Hope this helps.
