Electronic – Can two electrolytic capacitors be made into a bipolar?


I know if you put an electrolytic capacitor backwards they explode and it's quite fun to observe them exploding. I am wondering if you can use two of them (and some diodes) to turn it into a bipolar capacitor so it may be used with AC signals?

Best Answer

Yes. You can.

Connect in the following manner


Short both the -ve terminals. The other two +ve terminals can be used as leads of a non-polar capacitor.

I know that if you do like this the capcitance will reduce. I thinks it by 1/2.
