Welcome to Electronics Transistor Basics! This is a nonfiction science book which contains various topics on basics of transistor. A transistor is an electronic component that can be utilized in a variety of electronic devices because it can be used in circuits to either amplify or switch electrical signals or power. Two PN diodes connected back-to-back form a transistor. It has emitter, base, and collector terminals as its three terminals. The fundamental principle of a transistor is that it enables you to modify the intensity of a much smaller current that is flowing through a second channel in order to control the flow of current through one channel. Transistors are used extensively in daily life. They serve a purpose in almost every type of circuit in which they are utilized. Switches, amplifiers, oscillators, modulators, detectors, BJT, FET etc. are some of applications of transistors. This book contains various topics such as Bipolar Transistor, NPN Transistor, PNP Transistor, Transistor As A Switch, Junction Field Effect Transistor, MOSFET, MOSFET As A Switch, Darlington Transistors, Open Collector Outputs, FET Current Source and Transistor In A Brief. This is the first edition of the book. Thanks for reading the book.
