| Electrodeposition
|
|
Electrolytic process in which a metal is deposited at the cathode from a solution of its ions. |
| Electrodialysys
|
|
A process which uses an electrical current and an arrangement of permeable membranes to separate soluble minerals from water. It is often used to desalinate salt or brackish water. |
| Electrogas welding (egw)
|
|
Electric arc welding process, which uses a consumable solid or flux-cored electrode, either with or without an external shielding gas. |
| Electrolysis
|
|
A chemical reaction of a metal with another metal in the presence of an electrically conductive fluid, causing one to erode. |
| Electrolyte
|
|
A nonmetallic (liquid or solid) conductor that carries current by the movement of ions (instead of electrons) with the liberation of matter at the electrodes of an electrochemical cell. |
| Electromagnet
|
|
Mechanism, which is made of, a magnetic material wrapped with an electrically conductive coil through which the current is passed to bring about magnetism in the material. |
| Electromagnetic energy efficiency
|
|
Energy generated from an electromagnetic field produced by an electric current flowing through a superconducting wire kept at a specific low temperature. |
| Electromagnetic field (emf)
|
|
The electrical and magnetic fields created by the presence or flow of electricity in an electrical conductor or electricity consuming appliance or motor. |
| Electromagnetic spectrum
|
|
A continuum of electric and magnetic radiation that can be characterized by wavelength or frequency. Visible light encompasses a small part of the electromagnetic spectrum in the region from about 380 nanometers (violet) to 770 nanometers (red) by wavelength. |
| Electromechanical
|
|
Device combining electrical and mechanical components, for example as in an electric motor. |
