What is a diode?
In its simplest state, a diode is an electrical device that allows current to flow in one direction but not the other.
What is a diode made of?
Semiconductor diodes are constructed of layer of N-Type semiconducting material joined to a layer of P-Type semicondictor material. Beteen these is a depletion layer that varies in thickness depending of the voltage bias across the diode.
How does the structure of a diode relate to its circuit symbol?
