CHAPTER 5
Diodes, Rectifiers, and Zener Diodes
Resistors can work properly without regard to “polarity.” That is, in a circuit a resistor can be wired either way. For example, you can desolder the resistor from the circuit and flip the resistor leads and solder them back into the circuit and the circuit should work the same.
In this chapter, we will look at some basic two-terminal semiconductors. These are devices that require proper attention to how their leads are wired because their terminal leads have polarities. If you reverse a semiconductor’s lead, chances are that the circuit will not work at all, not work well, or not work the same (e.g., ...
