plural of electronic resource

(physics) Any of several electronic devices that control electron current through vacuum, gas or vapor between electrodes within a sealed container, usually of glass or metal and often designed to be easily installed in and removed from the equipment in which it is used.

(physics) A scanning transmission electron microscope that is able to focus electrons to a probe of about 0.14 nm and thus distinguish individual atoms.

(physics) An electron microscope that transmits a very narrow beam of electrons through a sample; it can detect individual large or heavy atoms.

(chemistry, physics) Any of several electrodes, having a thin glass bulb, whose potential is dependent upon the concentration of hydrogen or other ions in the solution in which it is immersed; used in pH meters etc.

An ion selective electrode used to measure the concentration of potassium ions, especially in biological fluids.

(chemistry, physics) An electrode whose potential is dependent on the concentration of a specific ion in the solution in which it is immersed.

A technique for painting metal structures that have many holes or cavities; paint is sprayed through a grid of wires that forms one electrode onto the structure to be painted which forms the other electrode, and to which the paint particles are attracted.

(physics) The potential energy of a system of separated electric charges.

(physics) The potential energy of an electric or magnetic field.
