capacitors!
@Felthry farads in a tube!
@Felthry oh true
still, they are cool little packages for temporary storage of voltage differences
@Felthry ooh, I have learned a word today.
@packbat it's extremely rare to the point that we've yet to encounter a professor who's familiar with it, which is kind of odd because it's not that rare that you need to talk about inverse capacitance? there's a lot of things with a 1/C term
@packbat though some of them are disks, or rectangles
