electrode (redirected from needle electrode)

e·lec·trode  (-lktrd)

n.

1. A solid electric conductor through which an electric current enters or leaves an electrolytic cell or other medium.

2. A collector or emitter of electric charge or of electric-charge carriers, as in a semiconducting device.

electrode  (-lktrd)

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.

Noun

1.

electrode - a conductor used to make electrical contact with some part of a circuit anode - a positively charged electrode by which electrons leave an electrical device base - (electronics) the part of a transistor that separates the emitter from the collector electric battery, battery - a device that produces electricity; may have several primary or secondary cells arranged in parallel or series cathode - a negatively charged electrode that is the source of electrons entering an electrical device collector - the electrode in a transistor through which a primary flow of carriers leaves the region between the electrodes conductor - a device designed to transmit electricity, heat, etc. electrolytic cell - a cell containing an electrolyte in which an applied voltage causes a reaction to occur that would not occur otherwise (such as the breakdown of water into hydrogen and oxygen) electron gun - the electrode that is the source of electrons in a cathode-ray tube or electron microscope; consists of a cathode that emits a stream of electrons and the electrostatic or electromagnetic apparatus that focuses it electronic equipment - equipment that involves the controlled conduction of electrons (especially in a gas or vacuum or semiconductor) emitter - the electrode in a transistor where electrons originate control grid, grid - an electrode placed between the cathode and anode of a vacuum tube to control the flow of electrons through the tube electron tube, thermionic tube, thermionic vacuum tube, thermionic valve, vacuum tube, tube - electronic device consisting of a system of electrodes arranged in an evacuated glass or metal envelope
