The negative end of an electric field The electrode in an electrochemical cell toward which cations flow and the electrode at which reduction occurs
One of two electrodes in a fuel cell or battery The cathode, the positive post of the fuel cell, has channels etched into it that distribute the oxygen to the surface of the catalyst It also conducts the electrons back from the external circuit to the catalyst, where they can recombine with the hydrogen ions and oxygen to form water
The part of a voltaic battery by which the electric current leaves substances through which it passes, or the surface at which the electric current passes out of the electrolyte; the negative pole; opposed to anode
a negatively charged electrode that is the source of electrons in an electrical device the positively charged terminal of a voltaic cell or storage battery that supplies current
The negative end of an electric field The electrode in an electrochemical cell toward which the cations flow and the electrode at which reduction occurs
(1) The negative electrode of an electric cell (2) The electron-emitting electrode of an electronic tube (3) The electron-rich electrode
Negatively charged electrode that receives electrons during electrolysis or plating Electrode upon which metals are plated from solution
A cathode is the negative electrode in a cell such as a battery. Compare anode. the negative electrode, marked (-), from which an electric current leaves a piece of equipment such as a battery anode (kathodos , from kata- ( CATACLYSM) + hodos ). Terminal or electrode at which electrons enter a system, such as an electrolytic cell or an electron tube. In a battery or other source of direct current, the cathode is the positive terminal. In a passive load it is the negative terminal. In an electron tube, such as a cathode-ray tube, electrons stream off the cathode and travel through the tube toward the anode. cathode ray oscilloscope cathode ray cathode ray tube
The electrode through which an electric current leaves a liquid, gas or other discrete part of an electric current; the negatively charged pole of an electrochemical cell
The positive electrode The electrode at which a reduction reaction (gain of electrons) occurs
In an electrochemical cell, the electrode where reduction is occurring; the negative electrode in an electrolytic cell and the positive electrode in a voltaic cell
The electrode where reduction occurs in an electrochemical cell It is the negative electrode in an electrolytic cell, while it is the positive electrode in a galvanic cell The current on the cathode is considered a negative current according to international convention; however, in electroanalytical chemistry the cathodic current is often considered positive Contrast with anode
Stream of electrons leaving the negative electrode, or cathode, in an evacuated or gas-filled discharge tube or emitted by a heated filament in certain electron tubes. Cathode rays cause fluorescent materials to luminesce and are utilized in cathode-ray oscilloscopes and television tubes (see cathode-ray tube)
vacuum tube which displays images when an electron beam falls on a phosphorescent surface (this technology is commonly used in computer monitors and televisions)
A cathode-ray tube is a device in televisions and computer terminals which sends an image onto the screen. Vacuum tube that produces images when its phosphorescent surface is struck by electron beams. CRTs can be monochrome (using one electron gun) or colour (typically using three electron guns to produce red, green, and blue images that, when combined, render a multicolour image). They come in a variety of display modes, including CGA (Color Graphics Adapter), VGA (Video Graphics Array), XGA (Extended Graphics Array), and the high-definition SVGA (Super Video Graphics Array)
a vacuum tube in which a hot cathode emits a beam of electrons that pass through a high voltage anode and are focused or deflected before hitting a phosphorescent screen
