Anodizing (spelled anodising in British English) is an electrolytic passivation process used to increase the thickness of the natural oxide layer on the surface of metal parts.
A cathode is the electrode from which a conventional current leaves a polarized electrical device.
The cathode ray tube (CRT) is a vacuum tube that contains one or more electron guns and a phosphorescent screen, and is used to display images.
Cathodic protection (CP) is a technique used to control the corrosion of a metal surface by making it the cathode of an electrochemical cell.
Corrosion is a natural process, which converts a refined metal to a more chemically-stable form, such as its oxide, hydroxide, or sulfide.
A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other.
In electromagnetism, there are two kinds of dipoles.
An electric battery is a device consisting of one or more electrochemical cells with external connections provided to power electrical devices such as flashlights, smartphones, and electric cars.
An electric current is a flow of electric charge.
Electrochemistry is the branch of physical chemistry that studies the relationship between electricity, as a measurable and quantitative phenomenon, and identifiable chemical change, with either electricity considered an outcome of a particular chemical change or vice versa.
An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air).
Electrode potential, E, in chemistry or electrochemistry, according to a IUPAC definition, is the electromotive force of a cell built of two electrodes.
In chemistry and manufacturing, electrolysis is a technique that uses a direct electric current (DC) to drive an otherwise non-spontaneous chemical reaction.
An electrolyte is a substance that produces an electrically conducting solution when dissolved in a polar solvent, such as water.
An electrolytic cell is an electrochemical cell that drives a non-spontaneous redox reaction through the application of electrical energy.
The electron is a subatomic particle, symbol or, whose electric charge is negative one elementary charge.
In physics, chemistry, and electronic engineering, an electron hole (often simply called a hole) is the lack of an electron at a position where one could exist in an atom or atomic lattice.
Electrostatics is a branch of physics that studies electric charges at rest.
A galvanic anode is the main component of a galvanic cathodic protection (CP) system used to protect buried or submerged metal structures from corrosion.
A galvanic cell, or voltaic cell, named after Luigi Galvani, or Alessandro Volta respectively, is an electrochemical cell that derives electrical energy from spontaneous redox reactions taking place within the cell.
Galvanization or galvanizing is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
A gas-filled tube, also known as a discharge tube, is an arrangement of electrodes in a gas within an insulating, temperature-resistant envelope.
A geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged, while geographic north and geographic south remain the same.
Greek (Modern Greek: ελληνικά, elliniká, "Greek", ελληνική γλώσσα, ellinikí glóssa, "Greek language") is an independent branch of the Indo-European family of languages, native to Greece and other parts of the Eastern Mediterranean and the Black Sea.
The hull is the watertight body of a ship or boat.
Sir Humphry Davy, 1st Baronet (17 December 177829 May 1829) was a Cornish chemist and inventor, who is best remembered today for isolating, using electricity, a series of elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as discovering the elemental nature of chlorine and iodine.
An ion is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons).
Iron is a chemical element with symbol Fe (from ferrum) and atomic number 26.
Michael Faraday FRS (22 September 1791 – 25 August 1867) was an English scientist who contributed to the study of electromagnetism and electrochemistry.
A mnemonic (the first "m" is silent) device, or memory device, is any learning technique that aids information retention or retrieval (remembering) in the human memory.
A plate, usually called anode in Britain, is a type of electrode that forms part of a vacuum tube.
A primary cell is a battery that is designed to be used once and discarded, and not recharged with electricity and reused like a secondary cell (rechargeable battery).
Redox (short for reduction–oxidation reaction) (pronunciation: or) is a chemical reaction in which the oxidation states of atoms are changed.
A semiconductor material has an electrical conductivity value falling between that of a conductor – such as copper, gold etc.
A solenoid (/ˈsolə.nɔɪd/) (from the French solénoïde, derived in turn from the Greek solen ("pipe, channel") and eidos ("form, shape")) is a coil wound into a tightly packed helix.
Steel is an alloy of iron and carbon and other elements.
Sulfuric acid (alternative spelling sulphuric acid) is a mineral acid with molecular formula H2SO4.
In electronics, a vacuum tube, an electron tube, or just a tube (North America), or valve (Britain and some other regions) is a device that controls electric current between electrodes in an evacuated container.
William Whewell (24 May 1794 – 6 March 1866) was an English polymath, scientist, Anglican priest, philosopher, theologian, and historian of science.
A Zener diode is a particular type of diode that, unlike a normal one, allows current to flow not only from its anode to its cathode, but also in the reverse direction, when the Zener voltage is reached.
Zinc is a chemical element with symbol Zn and atomic number 30.
