Exempel på hur man kan använda ELECTRODE i en mening

• An anode is an electrode of a polarized electrical device through which conventional current enters the device.
• If an evacuated glass tube is equipped with two electrodes and a voltage is applied, glass behind the positive electrode is observed to glow, due to electrons emitted from the cathode (the electrode connected to the negative terminal of the voltage supply).
• A cathode is the electrode from which a conventional current leaves a polarized electrical device such as a lead-acid battery.
• Compactrons are a type of vacuum tube, which contain multiple electrode structures packed into a single enclosure.
• The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity.
• Developed from Lee De Forest's 1906 Audion, a partial vacuum tube that added a grid electrode to the thermionic diode (Fleming valve), the triode was the first practical electronic amplifier and the ancestor of other types of vacuum tubes such as the tetrode and pentode.
• In electrochemistry, electrode potential is the voltage of a galvanic cell built from a standard reference electrode and another electrode to be characterized.
• The data below tabulates standard electrode potentials (E°), in volts relative to the standard hydrogen electrode (SHE), at:.
• This may allow chemicals, drugs, electrode arrays or DNA to be introduced into the cell (also called electrotransfer).
• It is a plasma propulsion engine using perpendicular electric and magnetic fields to accelerate a propellant with no electrode.
• If an electric potential is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons.
• The part to be coated acts as the cathode (negative electrode) of an electrolytic cell; the electrolyte is a solution of a salt whose cation is the metal to be coated, and the anode (positive electrode) is usually either a block of that metal, or of some inert conductive material.
• A spark plug has a metal threaded shell, electrically isolated from a central electrode by a ceramic insulator.
• These have tips suitable for piercing semi-solids, have electrode materials compatible with ingredients in food, and are resistant to clogging.
• Electroplating, a process that uses electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode.
• A cold-cathode vacuum tube does not rely on external heating of an electrode to provide thermionic emission of electrons.
• The Biefeld–Brown effect is an electrical phenomenon, first noticed by inventor Thomas Townsend Brown in the 1920s, where high voltage applied to the electrodes of an asymmetric capacitor causes a net propulsive force toward the smaller electrode.
• Whewell coined, among other terms, scientist, physicist, linguistics, consilience, catastrophism, uniformitarianism, and astigmatism; he suggested to Michael Faraday the terms electrode, ion, dielectric, anode, and cathode.
• Shielded metal arc welding (SMAW), also known as manual metal arc welding (MMA or MMAW), flux shielded arc welding or informally as stick welding, is a manual arc welding process that uses a consumable electrode covered with a flux to lay the weld.
• Hetero charge means that the polarity of the space charge is opposite to that of neighboring electrode, and homo charge is the reverse situation.
