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.
Operation is at atmospheric pressure and room temperature.
3. A type of chemical bonding in which one or more electrons are transferred completely from one atom to another, and so converting the neutral atoms into electrically charged ions.
These ions are approximately spherical and attract one another because of their opposite charge.
2. A record produced by an ionosonde (pulsing radar device that measures the height of ionospheric layers), plotting radio frequency against the round-trip time of each pulse.
3. The densitometer tracing generated by analyzing a strip of electrophoretically separated proteins.
2. A potentiometric electrode (electromotive force or pressure in an electric circuit measured in volts) that develops a potential in the presence of one ion (or class of ions), but not in the presence of a similar concentration of other ions.
2. An electroencephalogram or the graphic recording of the electric discharges of the cerebral cortex as detected by electrodes on the surface of the scalp in which no recognizable waveforms or deviations from the baseline of electrical activity can be discerned as arising from the brain.
3. A graphic chart on which no tracings are recorded during electroencephalography, indicating a lack of brain wave activity.
Flat readings are indicative of brain death except in cases of profound hypothermia and central nervous system depression.
In double refraction, the index of refraction (a measure of the amount the ray is bent on entering the material), and hence the wave velocity of light vibrating in the direction of the electric field, is slightly different from the index of refraction of the vibration perpendicular to it.
Optically, the substance behaves like a crystal with its optic axis parallel to the electric field.
This effect was discovered in the latter part of the 19th century by a Scottish physicist, John Kerr.
The same behavior in solids is sometimes called the Pockels effect.
The liquid membrane is physically supported by an inert porous matrix; such as, cellulose acetate.
2. The crumbling of a urinary calculus or gallstone within the body, followed at once by the washing out the fragments: The stone fragments that result from lithotripsy become small enough to be expelled during the urination process.
2. A unit of energy commonly used in nuclear and particle physics, equal to the energy acquired by an electron in falling through a potential of 106 volts.
