Magic Crystals and Magic Potions …. no just a real diode.

This post has been corrected – Somehow I managed to calculate the resistance of the diode and moved the decimal point.

The Symbol for a Diode

In last night’s post I got us to the point where a PN junction was formed on a single pure silicon crystal by doping one part of it
