Bipolar capacitor question
Hi I'm building the Project 27 on the official boards and it requires two bipolar electrolytic capacitors. Can't I achieve this by connecting two elect caps in series with the positive ends tied together?
I need a 1 uf cap and a 2.2 uf cap. Both bipolar. What value elec caps do I need to use to make bioplar 1 uf and 2.2 uf caps? Thanks a lot. |

The calculation of capacistance is opposit of resistance.
To make one 1 uF bipolar cap you must use two 2uF (2.2uF) connected in series. For the 2.2 uF it will be two 4.7uF caps.

Your better off trying to find actual bipolars. You can use 2 polars of equal value to make a bipolar by combining the cathodes together. Calculating series capacitance is the same as calculating parallel resistance as has been stated.

rod elliot recommends bipolar elec caps. I don't know why he does so, but I'm trying to build this project exactly. Would using a nonpolar film type be any different from the bipolar elec types?

. You must keep the values equal. To calculate, capacitors in series are like resistors in parrallel. Capacitors in parrallel, like resistors in series.
