electrode

تعريف electrode في الإنجليزية الإنجليزية القاموس.: the terminal through which electric current passes between metallic and nonmetallic parts of an electric circuit; a collector or emitter of electric charge in a semiconducting device; any terminal that conducts an electric current into or away from various conducting substances in a circuit (such as the anode or cathode of a battery); A conductor (not necessarily metallic) used to establish electrical contact with a non-metallic portion of a circuit Electrodes would be an integral part of ultra-high-power (UHP) transformers in a steel plant (Source: Mintzer, 1992); A CONDUCTOR used to establish electrical contact with a nonmetallic part of a circuit; A conductor by which electrical current enters or leaves a non-metallic medium, such as the electrolyte in a battery (as well as vacuum tubes and lots of other devices); A conductor through which current enters or leaves an electrolytic cell, at which there is a charge from conduction by electrons to conduction by charged particles of matter, or vice versa; The terminal in electric apparatus that conducts electricity in or out; Electrical terminal that conducts an electric current into or out of a fuel cell; An electrode is a small piece of metal or other substance that is used to take an electric current to or from a source of power, a piece of equipment, or a living body. The patient's brain activity is monitored via electrodes taped to the skull. a small piece of metal or a wire that is used to send electricity through a system or through a person's body (electro- + hodos ). Electric conductor, usually metal, used as one of two terminals to conduct electric current through a conducting medium. A simple voltaic cell, or battery, consists of two electrodes, usually one zinc and one copper, immersed in an electrolytic solution (see electrolyte). When a chemical reaction occurs in the solution, electrons gather on the zinc electrode, or cathode, which becomes negatively charged. At the same time, electrons are drawn from the copper electrode, the anode, giving it a positive charge. The difference in charge sets up a potential difference, or voltage, between the two electrodes. When they are connected by a conducting wire, electrons flow from the cathode to the anode, producing a current; The device through which current is conducted thru to the arc or base metal during the process of welding; An electrical conductor through which an electric current enters or leaves a conducting medium, whether it be an electrolytic solution, solid, molten mass, gas, or vacuum For electrolytic solutions, many solids, and molten masses, an electrode is an electrical conductor at the surface of which a change occurs from conduction by electrons to conduction by ions For gases and vacuum, the electrodes merely serve to conduct electricity to and from the medium; a Metal-Arc Filler metal in the form of a wire or rod, whether bare or covered, through which current is conducted between the electrode holder and the arc; the terminal at which electricity passes from one medium into another, such as in an electrical cell where the current leaves or returns to the electrolyte; a conductor used to make electrical contact with some part of a circuit; Conductor by which electric current enters or leaves an electrolyte in electrolysis; A conductor through which a current enters or leaves an electrolytic cell, vacuum tube, or any nonmetallic conductor; The path by which electricity is conveyed into or from a solution or other conducting medium; esp; a conductor used to make contact with a non-conducting part of a circuit; A conducting element in an electric cell, electronic tube, or semiconductor device; An anode (+) or cathode (-) conductor on a device through which an electric current passes; Conducting body at which the electrochemical reaction occurs; {i} electrical conductor, part of an electrical circuit; pole of an electric battery; Any conductor through which an electric current enters or leaves an electrolyte The casing and central cap of a torch battery are electrodes The lead plates in a car battery (with dilute sulphuric acid as the electrolyte) are electrodes; In an electrochemical cell, the location at which electric charge enters or leaves a metallic surface (see also anode and cathode) [back] [top]; a solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium It collects or emits electric charge, and is often used for detecting electrical impulses in the brain or muscles or transmitting signals in a bionic device Submitted by Jeffrey S Fox, foxjeff1@pilot msu edu; in piezoelectric and similar systems, the means, usually thin metal plates, by which electrical energy is introduced to the faces of the transducer crystals; = A conductor through which current enters or leaves an electrolytic cell at which there is a change from conduction by electrons to conduction by charged particles of matter or vice versa; 1 A terminal at which electricity passes from one medium into another The positive electrode is called anode; the negative electrode is called cathode; the ends of the wires or conductors, leading from source of electricity, and terminating in the medium traversed by the current; An electrical lead or wire attached to any electronic device or circuit through which current may flow in or out; An electrically conductive structure in an electrochemical device, such as a fuel cell, which transfers electrons to or from reactant atoms or molecules search
