Anode definition is - the electrode of an electrochemical cell at which oxidation occurs: such as.
The definition of anode and cathode is slightly different for electrical devices such as diodes and vacuum tubes where the electrode naming is fixed and does not depend on the actual charge flow (current). These devices usually allow substantial current flow in one direction but negligible current in the other direction.
Anode definition, the electrode or terminal by which current enters an electrolytic cell, voltaic cell, battery, etc. See more.
The anode and cathode are defined by the flow of current.In the general sense, current refers to any movement of electrical charge. However, you should keep in mind the convention that current direction is according to where a positive charge would move, not a negative charge. So, if electrons do the actual moving in a cell, then current runs the opposite direction.
anode: An anode is the electrode in a polarized electrical device through which current flows in from an outside circuit .
Define anode. anode synonyms, anode pronunciation, anode translation, English dictionary definition of anode. n. 1. A positively charged electrode, as of an electrolytic cell, storage battery, diode, or electron tube. 2. The negatively charged terminal of a primary...
Before we learn about cathode and anode we need to first understand what an electrode is. As per the general definition, an electrode is a substance that helps in the conduction of electricity wherein the electric current either enters or leaves the non-metallic medium like an electrolytic cell.. In simple terms, an electrode is a conductor that helps in establishing electrical contact with a ...

The anode is treated in a special manner so as to render it non-porous and impervious to attack by the nascent chlorine evolved on its surface. ...
Our definition of anode/cathode, as given in section~1, is simple and useful. The internal mechanism of a battery is not simple. It makes no sense to “explain” the former in terms of the latter. Battery terminals are labeled positive and negative. They are labeled according to voltage, not charge or current.
Cathode definition is - the electrode of an electrochemical cell at which reduction occurs:. ... "John B. Goodenough just became the oldest person, at 97, to win a Nobel Prize," 9 Oct. 2019 The cathodes and anodes of these batteries are made by mixing materials in a solvent (water or otherwise) ...
