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.

electropneumatic
Something which is moved by electric and pneumatic power.

The term pneumatic refers to operations by compressed air or gases in a tool or machine.

electropneumograph
An electrical apparatus that records respiratory (breathing) movements.
electropolar
Having one end or surface which is the positive end and the other end or surface is negative; such as, an electrical conductor.
electropolish
To polish metal with electrolysis or the decomposition of a chemical compound into its ions by the passage of an electrical current through a solution of an electrolyte.

Electrolytes include, acids, bases, and salts.

electropolishing, electrolytic polishing, electrolytic brightening,
1. Polishing a prosthesis by electroplating, that is, by adding metal, as opposed to the normal method of polishing, which removes metal, until the surface is flat.
2. The process whereby a metallic material is polished anodically (with positive electrodes or poles to which negative ions are attracted) in an electrolytic cell and it is often used on curved parts which can not be polished by normal mechanical procedures.
3. Smoothing and enhancing the appearance of a metal surface by making it an anode in a suitable electrolyte.
4. A method of polishing metal surfaces by applying an electric current through an electrolytic bath in a process that is the reverse of plating.

The metal to be polished is made the anode in an electric circuit.

The anodic dissolution of bumpy burrs and sharp edges occurs at a faster rate than over the flat surfaces and crevices, possibly because of locally higher current densities.

Such electrolytic polishing results in a superior flat, smooth, and brilliant surface.

electropositive
1. An element that can function as the positive electrode in an electric cell.
2. Relating to an atom or molecule that tends to provide electrons to an electron-acquiring substance; for example, metals are generally electropositive.
3. Charged with positive electricity, which results in the repulsion of bodies electrified positively and the attraction of bodies electrified negatively.
4. Capable of acing as the positive electrode in an electric cell.
electropositive atom
An atom which readily yields electrons and so has the tendency to acquire a partial positive charge in a covalent bond or to form a positive ion.
electropositive developer
A developer containing positively charged toner particles.
electropositive potential
1. The potential of an electrode expressed as positive regarding a hydrogen electrode.
2. An electrode's potential stated as positive in relation to the standard potential of the hydrogen electrode that is established at zero.
electroprosthesis
A prosthetic device which delivers patterned electrical stimuli to a peripheral nerve or brain site for a functionally beneficial effect.
electropsychometer, E-meter (s) (noun)
An electronic device manufactured by the Church of Scientology at their Gold Base production facility: "Known as an "E-meter", the electropsychometer measures changes in the electrical resistance of the human body by inducing a tiny electrical current through it."

"The face of the electropsychometer has a galvanometer that indicates changes in the person's resistance. According to Scientology doctrine, the resistance corresponds to the mental mass and energy of the subject's mind, which changes when the individual thinks of particular mental images or engrams (unconscious, painful memories)."

"These concepts are not validated by other scientists outside of Scientology; the action of the E-meter is more commonly attributed to galvanic skin response, an effect that is used in lie detectors."

electropulse engine
1. A flight vehicle engine utilizing spark discharges through which intense electric and magnetic fields are established, for periods ranging from microseconds to a few milliseconds, generating an electromagnetic force which drives plasma along the leads and away from the spark gap.
2. An engine set up for propelling a flight vehicle which is based on the use of spark discharges through which intense electric and magnetic fields are established for times ranging from microseconds to a few milliseconds.

A resulting electromagnetic force drives the plasma along the leads and away from the spark gap.

electropuncture (s) (noun) (no pl)
The use of needles as electrodes during surgery; Electropuncture is a therapy whereby electric currents are passed through a person't body by way of electrodes on the skin.

electropyrexia, inductopyrexia
1. The production of high body temperature, or artificial fever, by means of electric currents.
2. An artificial fever induced by electrical means for therapeutic purposes; such as, fever therapy.
electroradiologist
A former term for radiologist.
