Description: Low cost consumer device trade-offs for reverse polarity and over current protection. The previous version of this video had errors in the schematic which are now corrected. I slipped up and several volts across the diode. Meant to say several tenths of a volt 0.2V - 0.7V A Viewer spotted that I said voltage flows through the diode.. Nope. Should've said current. Difficult to do these quick videos in a single take. Nerd Thunder: Big Clive - youtube.com/watch?v=AOCrG0mOMW4 EEVLOG - youtube.com/watch?v=eOWtrO04NOk
