Lesson 4 Using Transistors: Let’s Get Transistorized! Overview In this lesson, students build two circuits and explore how transistors function. Objectives • To observe how a transistor ...

The transistor tester is a GM328A made for various transistor testing applications, but is also an LCR meter.

The remaining three pins are used for programming a built-in switch matrix. You can create circuits with the MOSbius by connecting the pins with external wires. But it’s easier to use the switch ...

Protection: The 2.2kΩ resistor in the circuit protects the transistor from being damaged by too high a voltage or current. The transistor needs 0.6V on the base leg to switch on.

With the invention of the integrated circuit, or microchip, in which thousands or millions of transistors are deposited on a piece of silicon, transistors have become microscopic.
