Dec 4, 6. Hi Beenthere So to summarise in terms of my question - the cathode negative marked leg goes to Ground and the Anode possibly marked positive goes to the 12v or 5v side? I know whomever first decided that electrical charge was a fluid decided it flowed one way but it the electrons actually flow the other way. This continually confuses me. I know I am being really thick here, but I need this spelled out for me. Dec 4, 7. They are NOT called cathode and anode, as they do with diodes. Dec 4, 8.

Nice one Thanks bertus. Dec 4, 9.
Hello All I need to connect a number of decoupling capacitors and am One important difference in polar capacitors is that electrolytic caps. You can connect a non-polarized component in any direction, and it'll function integrated circuits, transistors, voltage regulators, electrolytic capacitors, and.

No, create an account now. Yes, my password is: On a contrary note, see also this answer to another related question on this site, where Kortuk has a contrary opinion in the comments, against using normal electrolytic capacitors back to back. While that viewpoint has been put forward in discussion, I have been unable to find any academic study substantiating the concern. That is not to say that such a study or reference does not exist.
I do find several references to applying normal back to back capacitors for non-polarized functioning, and have used this myself for many years in various designs, with never a single failure. The only caveat I adhere to, is to not approach within shouting distance of the rated voltage for each of the capacitors, if using them this way. Home Questions Tags Users Unanswered. Can two electrolytic capacitors be made into a bipolar?
Can you make a non-polar electrolytic capacitor out of two regular electrolytic capacitors? PeterJ 16k 20 42 Just that there has to be a net DC bias across them. For situations where you can't guarantee a bias of particular polarity or one that contains the signals wing, there are off-the-shelf non-polar electrolytics you can use. So why do this.
Capacitors play a significant role in the family of passive electronic components, and their uses are everywhere. It displays wide, smart, zoom and mfd sizes such as. Everyone and every web page states this, but does not say which way round is the correct polarity!! How an Optocoupler Works An optocoupler works to safely separate high-voltage components and low-voltage devices while removing electrical noise in electronic devices. Capacitors come in a variety of shapes and sizes, all of which determine how well they can hold a charge. Apr 20, 15,
Probably because you're more likely to already have polarized ones on hand. Connect in the following manner -- -- -- Short both the -ve terminals. I know that if you do like this the capcitance will reduce. Do not do this. There's a lot of theory talk going on in this question.
Which way to connect a capacitor? - really basic question.
I'm going to take some measurements and blow up some caps. Anindo Ghosh Anindo Ghosh The reason for this is that two caps are never identical and it is possible that the middle node gets out of whack. This bias removes the issue that Kortuk raises, and keeps both caps from being reverse biased.
