Electrode - Wikipedia 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 a gas) In electrochemical cells, electrodes are essential parts that can consist of a variety of materials (chemicals) depending on the type of cell
Electrode | Conductors, Reactions Cells | Britannica Electrode, electric conductor, usually metal, used as either of the two terminals of an electrically conducting medium; it conducts current into and out of the medium, which may be an electrolytic solution as in a storage battery, or a solid, gas, or vacuum
Explainer: What is an electrode? - Science News Explores electrode: A device that conducts electricity and is used to make contact with non-metal part of an electrical circuit, or that contacts something through which an electrical signal moves (in electronics) Part of a semiconductor device (such as a transistor) that either releases or collects electrons or holes, or that can control their movement
What is Electrode? - BYJUS What is Electrode? Electrodes can be defined as conductors that are used to make electrical contact with a non-metallic part of the circuit The term was first coined by William Whewell and derived from Greek words Elektron, which means “amber” and hodos which translates to “a way ”
Electrode - Energy Education An electrode is a conductor that is used to make contact with a nonmetallic part of a circuit Electrodes are commonly used in electrochemical cells (see Figure 1), semiconductors like diodes, and in medical devices The electrode is the place where electron transfer occurs
What is Electrodes? - Definition, Types and Advantages - EEEGUIDE An electrode is a piece of wire or rod (of a metal or alloy), with or without flux covering, which carries current for welding At one end it is gripped in a holder and an arc is set up at the other end
Definition of electrodes - Chemistry Dictionary An electrode is a solid electric conductor that carries electric current into non-metallic solids, or liquids, or gases, or plasmas, or vacuums Electrodes are typically good electric conductors, but they need not be metals
