A capacitor in my ceiling fan failed. I was hunting for this replacement:
but at first I only found this:
I was wondering if the second one would work if I just capped off the red wire and didn't attach it to anything. With no potential difference across the third capacitor, it never stores any energy right?
Is my dim memory of idealized freshman physics correct? Even if it is, is there some real-world effect that would make doing this wrong in practice? (Don't worry! I found the exact replacement, so I'm not actually going to use the second one. I'm just curious.)
