Bipolar transistors can be either npn type or pnp type. There are two distinct types of transistor, the bipolar transistor and the MOSFET, and for each type of transistor there are two varieties. Transistors are devices that require only small input currents or voltages but can handle large output currents. Something needs to allow the process devices to work with the output transducers and this is where transistors are used. The output transducers may, on the other hand, require larger currents (several amps) and work at higher voltages. The devices used to perform the various processes are often small low power ICs that can only source or sink relatively small currents (several mA) and work at fairly low voltages. By considering a systems approach to electronics, processes such as counters and logic circuits often need to drive larger output devices such as bulbs, motors and heaters etc. The above is a fairly concise description of what transistors do. They deal with electrical power in response to electrical signals. Transistors are devices that are used to drive output transducers.
