Guide for Tech Beginners - Transistor

Transistors can be regarded as a type of electronic switch, as can many electronic components. Transistor is much more faster than mechanical switch. There are two types of basic transistor out there: bi-polar junction (BJT) and metal-oxide field-effect (MOSFET), and there are actually two versions of the BJT: NPN and PNP. Most circuits tend to use NPN. There are hundreds of transistors which work at different voltages but all of them fall into these two categories. Transistors are manufactured in different shapes but they have three leads (legs). The BASE - which is the lead responsible for activating the transistor.The...
