Title: Calculating the Energy in a Capacitor
Post by: EEVblog on June 01, 2021, 04:45:23 am
Only Dave can turn a dumpster whiteboard find test video into a tutorial on deriving the equation for the energy in a capacitor.
And shot in 4K because Dave didn't check the camera beforehand.

I actually like the layout of the vertical whiteboard.  Maybe just crop it in a little bit tighter like this (same aspect ratio), and slightly raise the whiteboard

One of the benefits of shooting in 4K, you can reframe in post without losing too much clarity on the 1080p upload.

Yes, I wouldn't frame it like that in a real video, too wasteful. That basically turns it into a square whiteboard.
