Introduction Transistors make our electronics world go ‘round. They’re critical as a control source in just about every modern circuit. Sometimes you see them, but more-often-than-not they’re hidden deep within the die of an  integrated circuit . In this tutorial we’ll introduce you to the basics of the most common transistor around: the bi-polar junction transistor (BJT). In small, discrete quantities, transistors can be used to create simple electronic switches,  digital logic , and signal amplifying circuits. In quantities of thousands, millions, and even billions, transistors are interconnected and embedded into tiny chips to create computer memories, microprocessors, and other complex ICs. Covered In This Tutorial After reading through this tutorial, we want you to have a broad understanding of how transistors work. We won’t dig too deeply into semiconductor physics or equivalent models, but we’ll get deep enough into the subject that you’ll understand h...

There are many different types of resistor available for use within electronic circuits. These different resistor types have somewhat different properties dependent upon their construction and manufacture. This makes the different types of resistor suitable for different applications. Over the years the resistor types used in mass electronics production have changed. Years ago, all the resistors used had leads and were relatively large, and by today's standards they offered a low level of performance. Today, the resistor types used are much smaller and offer much higher levels of performance. Fixed & variable resistor types The first major categories into which the different types of resistor can be fitted is into whether they are fixed or variable. These different resistor types are used for different applications: Fixed resistors:    Fixed resistors are by far the most widely used type of resistor. They are used in electronics circuits to set the right con...
