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. An electrochemical recording in which the chemical change is made possible by the presence of an electrolyte.
2. A rectifier consisting of metal electrodes in an electrolyte, in which rectification of alternating current is accompanied by electrolytic action.
Polarizing film formed on one electrode permits current flow in one direction but not in the other direction.
2. A rheostat which consists of a tank of conducting liquid in which electrodes are placed, and resistance is varied by changing the distance between the electrodes, the depth of immersion of the electrodes, or the resistivity of the solution.
2. A solution made up of a solvent and a dissociated ionic solute.
It will conduct electricity, and ions can be separated from the solution by deposition on an electrically charged electrode.
2. A switch having two electrodes projecting into a chamber partly filled with electrolyte, leaving an air bubble of a predetermined width.
The bubble shifts position and changes the amount of electrolyte in contact with the electrodes when the switch is tilted from a true horizontal.
2. A tank in which voltages are applied to an enlarged scale model of an electron-tube system or a reduced scale model of an aerodynamic system immersed in a poorly conducting liquid.
The equipotential lines between electrodes are traced with measuring probes, as an aid to electron-tube design.
It is also used as an aid to electron-tube design or in computing ideal fluid flow.
2. A process in which electric energy causes a chemical change in a conducting medium, usually a solution or a molten substance, or the decomposition of a substance such as hair follicles.
2. To use electrolysis to decompose a chemical compound.
2. An instrument for removing fibromas (benign tumors composed primarily of fibrous connective tissues) or relieving urethral strictures (abnormal narrowing of bodily canals or passageways) by electrolysis.
3. An electrolytic cell that produces alkalies, metals, chlorine, or other related products.
The current is being carried, or was carried, in the electrolyte by ions which are migrating, or migrated, to the electrodes where they could react, forming new substances.
