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 branch of metallurgy which deals with the processing of metals to reduce metallic compounds by means of electricity.
3. The art and the science of extracting and refining metal values from ores by electrical or electrochemical processes.
4. The process dealing with the use of electricity for smelting or refining of metals.
The electrochemical effect of an electric current brings about the reduction of metallic compounds, and thereby the extraction of metals from their ores (electrowinning) or the purification of the metals (electrorefining).
2. An instrument for detecting or determining the magnitude of a potential difference or charge by the electrostatic forces between charged bodies.
3. A fundamental instrument in which potential is measured by the attraction between two oppositely charged disks.
4. An instrument for measuring the quantity or intensity of electricity; also, sometimes, and less properly, applied to an instrument that indicates the presence of electricity; also called an electroscope.
5. An instrument used to determine fluctuations in electrostatic potential difference between charged electrodes due to radiation.
2. A low-noise amplifier having sufficiently low current drift and other characteristics required for measuring very low currents.
2. A high-vacuum electron tube having a high input impedance (low control-electrode conductance) to facilitate the measurement of extremely small direct currents or voltages.
2. Any of several types of instruments which are actuated by the forces between charged bodies and are used to indicate the presence of ionizing radiation and to measure potential differences; for example, an electroscope.
2. In medicine, an instrument which can record changes in the electrical potentials of uterine muscles.
It causes voids (empty spaces) in the conductor that can grow until current flow is blocked.
Its destructive effects are aggravated at high temperature and high-current flow, but these effects can be minimized by limiting current densities and alloying the aluminum with copper or titanium.2. A detrimental effect occurring in transistors employing aluminum metallization schemes.
Electromigration of aluminum results from the mass transportation of metal by momentum exchanges between thermally activated metal ions and conduction electrons.
When it occurs, the ideally uniform aluminum film reconstructs to form thin conductor regions and extruded-like hillocks (hills or bumps) that may cause the transistor's destruction.
2. Relating to the transfer of mass which occurs in a metal as a result of the movement of ions under the influence of an electrical current.
3. Pertaining to a procedure that is used to separate isotopes; as in chemistry.
2. The process of modulation spectroscopy in which changes are measured during the transmission or the reflection spectra produced by modifying an electric field.
2. A mechanical action, motion, or force produced by an electric current.
2. Relating to or producing an electric current or electric action.
3. A reference to the passage of electricity in a current or a motion produced by it.
