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. A platinum wire electrode used in measuring arterial blood oxygen.
When a current of an appropriate voltage is applied, oxygen flows from the specimen through a gas-permeable membrane and is destroyed at the platinum surface.
2. An instrument which converts light into electrical energy or uses it to regulate a flow of current, often incorporated into automatic control systems for doors and lighting.
3. An electronic device having an electrical output that varies in response to incident radiation; especially, to visible light.
4. A small cathode-ray tube having a fluorescent pattern whose size varies with the voltage applied to the grid.
It is used in radio receivers to indicate accuracy of tuning and as a modulation indicator in some tape recorders.5. An electric eye can operate a mechanism so as to open a door when its invisible beam is interrupted by the approach of a person and includes a photoelectric cell which is used as an automatic controlling appliance.
It is also used in motion pictures, television, and many other industries.
2. Relating to, or produced by, the electrical effects of light, including the emission of electrons, the generation of a voltage, or a change in resistance.
The classical concept of light as a continuous wave could not account for this, and it was then explained by Einstein (1905) on the basis that light is a stream of separate particles.
This interpretation, and his subsequent elaboration of it, is said to have formed the basis for much of quantum mechanics.
