The most basic and the most common application of transistors is as
an amplifier.
Transistors may be configured to amplify voltage,
current, or power as needed.
Figure 1-43 shows a basic transistor
amplifier circuit.

Many types of special purpose transistors have been developed (and
continue to be developed).
The identification of transistors is
often critical in the repair of electronic equipment.
