Electrodes used in shielded metal arc welding. 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). Electrodes are essential parts of batteries that can consist of a variety of materials (chemicals) depending on the type of battery.. The electrophore, invented by Johan Wilcke, was an early ...
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.”
Explainer: What is an electrode? Simplifying the sometimes-confusing terms that describe where electricity meets chemistry. All batteries have a negatively charged anode at one end and a positively charged cathode at the other end. These are their electrodes. Peter Dazeley/The Image Bank/Getty Images. By Adrian Dingle.

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.

An Electrode can be defined as the point where current either enters or leaves the electrolyte or circuit. When the current leaves the Electrode it is known as the cathode while when the current enters the Electrode it is known as an anode. Electrodes are the main component of electrochemical cells.
1. : a conductor used to establish electrical contact with a nonmetallic part of a circuit. 2. : an element in a semiconductor device (such as a transistor) that emits or collects electrons or holes or controls their movements.
An electrode is a conductor that is used to make contact with a nonmetallic part of a circuit. [1] 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.
An electrode is a conductor that passes an electrical current from one medium to another, usually from a power source to a device or material.
