Problem 3.1
Show the graphical symbol and general design of a diode used in electrical schematic diagrams. Identify the anode and cathode to show the polarity of the diode.
Problem 3.3
Define a Zener diode, its other names, and how it is generally used. Show a graph of a volt/ampere properties for a 5.6-V Zener diode.
A Zener diode functions like a normal diode in the normal orientation. However, in the reverse polarity, that is with the band or cathode side to the positive input, the diode has what is called the Zener breakdown voltage. At this voltage the diode becomes conductive and allows current to flow through it.
