![]() You just want to make sure to install the cap correctly. If the cap is installed incorrectly, it's still true, you are just going to kill the cap. It's is true of all parts of all circuits all of the time. This is hardly earth shattering knowledge. In actuality, the electrons are going to flow from the more negative side, however marked, to the the more positive side. Regardless of marking, if you have the cap installed correctly the unreal "current" is going to flow from the more positive side, however marked, to the more negative side. With these types of caps, conventional current would flow INTO the arrow, meaning into the positive side, correct?Įlectron flow would obviously be the opposite and current would flow through the cap WITH the arrow. Some (not all) of the electrolytic caps I've seen, have an arrow pointing to the positive terminal (which I guess I incorrectly correlated to the anode). Tantalums are polarized too, but the more postive leg is marked and there is no difference in the leg length. Longer is for the positive side, shorter with the grey bar and the negative sign is for the negative side. An electrolytic cannot span two logic wires because the polarity would be incorrect at least part of the time which is a bad, disallowed, dangerous, and will kill the cap. But I don't think you see that setup very often at all. ![]() That way it will never be reversed biased, only evenly biased. If it spans a logic wire and +5V connect the longer side to the +5V and the shorter (-) side to the logic wire. If it spans a logic wire and ground connect the longer side to the logic wire, the shorter (-) side to the ground wire. ![]() Since these capacitors usually span between power and ground to provide noise surpression, it's generally easy to tell which is which. So if you have the regular +5V/0V power supply connect the longer leg to the +5V side and the shorter leg which will be marked something like (-) to the +0V side. Are you talking electron current, or conventional current?
