Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other electrically charged particles. Electronics is a subfield of physics [ 1][ 2] and electrical engineering which uses active devices such as transistors, diodes, and ...
The class of electronic devices handling power greater than a watt. power engineering. That part of electrical engineering that deals with the generation, distribution and consumption of electrical power. power-factor correction. Apparatus intended to bring the power factor of some load closer to 1. power factor.
Semiconductor device. A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum ...
A Radio Shack consumer electronics store in a mall. Consumer electronics or home electronics are electronic ( analog or digital) equipment intended for everyday use, typically in private homes. Consumer electronics include devices used for entertainment, communications and recreation. These products are usually referred to as black goods due to ...
Electrical device. Electric (al) devices are devices that functionally rely on electric energy ( AC or DC) to operate their core parts ( electric motors, transformers, lighting, rechargeable batteries, control electronics ). They can be contrasted with traditional mechanical devices which depend on different power sources like fuels or human ...
Optoelectronics. Optoelectronics (or optronics) is the study and application of electronic devices and systems that find, detect and control light, usually considered a sub-field of photonics. In this context, light often includes invisible forms of radiation such as gamma rays, X-rays, ultraviolet and infrared, in addition to visible light.
Electronics portal. Electronics is the study and use of electrical devices that operate at relatively low voltages by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The pure study of such devices is considered as a branch of physics, while the design and ...
Digital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics which work primarily with analog signals. Despite the name, digital electronics designs includes important analog design considerations.
