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 process in which the passage of an electric current through an electrolytic solution or other suitable medium produces a chemical reaction; such as, that which occurs in a battery.
3. The process of splitting water into its components, hydrogen, and oxygen; by means of an electrical current.
4. Any process in which the passage of an electric current through a solution or medium produces a chemical reaction.
5. The chemical decomposition of a substance by the reactions that occur to its constituent ions at electrodes when an electric current is passed through the molten substance or, more often, through a solution of the substance.
6. The production of chemical changes by passing electric current from an electrode to an electrolyte, or the reverse of such action.
It is also used to separate isotopes, as in the concentration of deuterium, or heavy water, by the electrolysis of ordinary water.7. One application of electrolysis is the permanent removal of body hair, including the hair roots, with an electronic instrument.
Although electrolysis is promoted as a permanent process, many people find that hair does grow back, although slowly, after electrolysis.
Electrolysis may be done by a dermatologist, by an electrolysis technician, or by a facial technologist or esthetician.
2. In the body, any ion in cells, blood, or other organic material.
Electrolytes help to control fluid levels in the body, maintain normal pH levels, and ensure the correct electric potential between nerve cells which enables the transmission of nerve signals.
Sodium, potassium,chloride, calcium, and phosphate are examples of electrolytes, informally known as lytes.
Electrolyte replacement is needed when a patient has prolonged vomiting or diarrhea, and as a response to strenuous athletic activity.
Commercial electrolyte solutions are available, particularly for sick children (solutions; such as, Pedialygte) and athletes (sports drinks; such as, Gatorade). Electrolyte monitoring is also important in the treatment of anorexia and bulimia
The loss of potassium ion by vomiting, by diarrhea, or the action of certain medications, including diuretics and corticosteroids, may be corrected by administering a solution high in potassium.
2. A reserve battery in which an aqueous electrolyte is stored in a separate chamber, and a mechanism, which may be operated from a remote location, drives the electrolyte out of the reservoir and into the cells of the battery for activation.
2. Referring to electrolytes or the process in which the passage of an electric current through a solution or medium produces a chemical reaction.
3. A reference to the destruction of living tissue; especially, of hair roots, by means of an electric current applied with a needle-shaped electrode.
2. A basic electrochemical technique for the quantitative analysis of conducting solutions containing oxidizable or reducible material.
The measurement is based on the weight of material plated out onto the electrode.
A thin layer of oxidation on the foil is the dielectric.2. A capacitor having an electrolyte between two plates.
A thin layer of oxide is deposited on only the positive plate. The oxide acts as the dielectric for the capacitor.
Electrolytic capacitors are polarized and so they must be connected in correct polarity to prevent a breakdown; so, although electrolytic capacitors have comparatively high values of capacitance for their sizes, they also have a high leakage of current and therefore must often have their polarities checked.
2. A cell consisting of electrodes immersed in an electrolyte solution, for carrying out electrolysis.
3. The electrolyte, its container, and the electrodes used in electrolysis.
4. A cell containing an electrolyte through which an externally generated electric current is passed by a system of electrodes in order to produce an electrochemical reaction which produces an electromotive force.
It can be used to store electric energy for use on demand, as in a storage cell; to generate electric energy, as in a dry cell; or to produce a desired electrochemical reaction when electric energy is applied.
2. A process of removing soil, scale, or corrosion products from a metal surface by subjecting it as an electrode to an electric current in an electrolytic bath.
