A practical demonstration of Lenz's law and back EMF in an inductive relay coil and how to solve it using a Freewheeling/Flywheel/Flyback/Snubber/Clamp diode. Also the downsides of clamping diodes, and switch arcing supression.
Also a look at an AMAZING potential phenomenon you probably haven't seen before!
Actually, two rather cool things you probably haven't seen before.
Along with transistor ratings, transistor storage current, and Collector-Emitter breakdown voltage, there is a lot to unpack in this video.
This is a follow-on from the DC Transients Fundamentals video:
