Electronic engineering – BASIC ELECTRONICS TUTORIAL

Electronics Engineering

Electronic engineering is a professional discipline that deals with the behavior and effects of electrons (as in electron tubes and transistors) and with electronic devices, systems, or equipment. The term now also covers a large part of electrical engineering degree courses as studied at most European universities. Its practitioners are called electronics engineers in …

SMD resistor

Resistor Resistor symbols (US and Japan) Resistor symbols (Europe, IEC) A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in accordance with Ohm’s law. (Certain ultra-precise resistors have 2 extra terminals, for a total of 4.) Applications • In …

Semiconductor A semiconductor is a solid whose electrical conductivity can be controlled over a wide range either permanently or dynamically. Semiconductors are tremendously important technologically and economically. Semiconductors are essential materials in all modern electrical devices, from computers to cellular phones to digital audio players. Silicon is the most commercially important semiconductor, though dozens …

Vacuum tubes on a Philco model 20 tabletop radio set.

In electronics, a vacuum tube or (thermionic) valve (outside North America) is a device generally used to amplify, or otherwise modify, a signal by controlling the movement of electrons in an evacuated space. For most purposes, the vacuum tube has been replaced by the much smaller and less expensive transistor, either as a …

Types of circuits – Basic electronics tutorial

Types of circuits

 Analog circuits Most analog electronic appliances, such as radio receivers, are constructed from combinations of a few types of basic circuits. Analog circuits use a continuous range of voltage as opposed to discrete levels as in digital circuits. The number of different analog circuits so far devised is huge, especially because a ‘circuit’ …
