electro-, electr-, electri-
(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)
Electronics in our lives consists of numerous tools
Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.
2. The relation between two of variables of an electron tube; such as, electrode voltage and electrode current of an electrode with all other voltages maintained constant.
2. An electronic apparatus that consists, typically, of a sealed glass bulb containing two or more electrodes.
It is used to generate, to amplify, and to rectify electric oscillations and alternating currents.3. An electron device in which electricity is conducted by electrons moving through a vacuum or gaseous medium within an hermetically sealed envelope.
A tube can perform rectification, amplification, modulation, demodulation, oscillation, limiting, and a variety of other activities.
Examples include cathode-ray tubes, gas tubes, phototubes, and vacuum tubes.
Such tools may be either gas filled, or partially or fully evacuated; such as,vacuums.
Common tubes include vacuum tubes, cathode-ray tubes, phototubes, mercury vapor tubes, thyratrons, and microwave tubes.
Thyratrons are gas-filled hot-cathode tubes which are used as electronic switches or relays in which signals applied to the control grids initiates anode currents but does not limit them and cannot interrupt, the flow of electrons.
2. The phenomena of a particle's ability to penetrate energy barriers within electronic structures.
2. A unit of energy defined as the kinetic energy acquired by an electron that is accelerated through a potential difference of one volt; equivalent to 1.6022 x 10-19 joules.
3. A unit of energy used in atomic and nuclear physics, equal to the energy gained by an electron.
4. A unit of electrical energy used in nuclear physics.
It is equal to the energy gained by an electron when it moves from one point to a point higher in potential by one volt and it is a unit of energy or work, not of voltage.
The square of the function's modulus gives the probability per unit volume of finding electrons at a given position.
2. The induction of unconsciousness by the application of electricity to the brain between electrodes placed on the temples.
3. Anesthesia that is induced or produced by passing precisely controlled electric current through the brain without causing convulsions: One example of electronarcosis is the treatment of psychiatric disorders.
2. Drilling of tiny holes in a ferrite, semiconductor, or other material by using a sharply focused electron beam to melt and evaporate or sublimate the material in a vacuum.
2. An electronic transducer, either fixed or adjustable, that reduces the amplitude of a wave without causing significant distortion.
Electron beam evaporation is a commonly used process for coating lenses and filters with anti-reflection, scratch-resistant or other specialized coatings.
The process is also commonly used for coating insulating and resistor films on electronic components.
