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?
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.
