Scientific definitions for electrode

electrode

[ ĭ-lĕk′trōd′ ]

A conductor through which an electric current enters or leaves a substance (or a vacuum) whose electrical characteristics are being measured, used, or manipulated. Electrodes can be used to detect electrical activity such as brain waves. Terminal points in electrical components such as transistors, diodes, and batteries are electrodes.
