And I replace the deodorant ball casters with much better, but still fairly lightweight, Pololu casters.

http://rimstar.orgLC Circuit: Selecting Coil and CapacitorRimstarOrg2017-04-27 | ERROR!!!! The correction is that whenever the capacitor is discharged, the current it at maximum. At 1:45, 2:37 and 2:49, I remove the arrows to indicate that the current is zero while the capacitor is discharged. I shouldn't have removed them. In fact the arrows are moving in the same direction before and after those points and the arrows are thickest, meaning maximum current! How can it possibly be maximum, then zero, then maximum?! My bad. It's shown better in the animations starting at 3:16.

The previous version of this video had an error in it that was too big to fix with an annotation, and so it was removed, fixed, enhanced and reuploaded. The error was a silly one on my part where I had the fault go to ground, silly because I should have realized that wasn't what happens since I knew about the ground being connected to the neutral bar in the breaker panel. A big thanks to all who brought it up in the comments to the previous version.
