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 …

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 For most purposes, the vacuum tube has been replaced by the much smaller and less expensive transistor, either as a …

Classifications of power electronics


Classifications A power device may be classified as one of the following main categories (see figure 1): A two-terminal device (e.g., a diode), whose state is completely dependent on the external power circuit to which it is connected. A three-terminal device (e.g., a triode), whose state is dependent on not only its …
