| Aug 9, 2021 at 1:06 | comment | added | jonk | If you multiply the pulse duration (in seconds) by the pulse current (in amps) you will get Coulombs. You can divide into that, the maximum voltage rise you can tolerate before the LEDs show something, to get a capacitance value: \$C=\frac{\Delta Q}{\Delta V}\$. Whether or not that's a useful value (and how to hook everything up, besides) is another issue. I'm not savvy about these auto circuits, and you've not posted something I could read to become educated about it either, so I'm not going to be much help beyond that. | |
