Previous set of "E" terms.
ELECTROMAGNET. An electrically excited magnet capable of exerting mechanical force or of
performing mechanical work.
ELECTROMAGNETIC. The term describing the relationship between electricity and magnetism. A
quality that combines both magnetic and electric properties.
ELECTROMAGNETIC FIELD. The combination of an electric (E) field and a magnetic (H) field.
ELECTROMAGNETIC INDUCTION. The production of a voltage in a coil because of a change in the
number of magnetic lines of force (flux linkages) passing through the coil.
ELECTROMAGNETIC INTERFERENCE. Man-made or natural interference that degrades the quality
of reception of radio waves.
ELECTROMAGNETIC RADIATION. The radiation of radio waves into space.
ELECTROMAGNETIC SPEAKER. A speaker that uses an electro-magnet. Refer to Graphic of an Electromagnet Speaker.
ELECTROMAGNETISM. The generation of a magnetic field around a current-carrying conductor.
ELECTROMOTIVE FORCE (emf). The force (voltage) that produces an electric current in a circuit.
ELECTRON. The elementary negative charge that revolves around the nucleus of an atom. Additional terms relating to Electron Definitions
ELECTRONIC-EQUIPMENT DEHYDRATOR. A device that provides an alternate dry-air input in the
event of failure of the central dry-air system. It may include a compressor.
ELECTRONIC FREQUENCY COUNTER. An instrument that counts the number of cycles (pulses)
occurring during a precise time interval. [Frequency Counter Manufacturers]
ELECTRONICS. The term electronics as defined is a
system, or equipment, with the primary purpose of which is the transmission or
reception, of intelligence, and includes or comprises, communications or
signal equipment, radio, radar, radiation, radio-controlling devices,
meteorological, fire-control, bombing, flight and navigational instruments,
power plant controls, synchronizers, photographic and test equipment [adopted from a Military airbourne specification]. Electronics employ circuits which utilize a combination of electrical or
electronic devices to generate,control,indicate,or record any form of
alternating or direct currents,or both.
ELECTRONIC SCANNING. Scanning in which the axis of the beam is moved, relative to the antenna
axis, in a desired pattern. Also see Technical Radar Terms
ELECTRONICS DRY-AIR BRANCH. A common line for providing dry air to various electronic
equipment, such as search radar, fire-control radar, and repeaters.
ELECTRONIC SWITCH. A circuit that causes a start-and-stop switching action by electronic means.
ELECTRONIC TUNING. In a reflex klystron, changing the frequency and output power of the tube by
altering the repeller voltage.
ELECTROSTATIC. Pertaining to electricity at rest, such as charges on an object (static electricity).
ELECTROSTATIC DEFLECTION. The method of deflecting an electron beam by passing it between
parallel charged plates mounted inside a cathode-ray tube [CRT Internal View and definitions].
Electrostatic Discharge Sensitive. (ESDS). The level of susceptibility of devices to damage by static electricity, found by classification testing, is used as the basis for assigning an ESDS class. Electronic parts having sensitive
characteristics (e.g., thin-layered internal composition) and delicate, miniaturized construction
which are susceptible to damage or degradation, in various degrees, from environmental field
forces (electrostatic, electromagnetic, magnetic, or radioactive). This susceptibility also extends
to the standard electronic modules, printed circuit boards, printed wiring boards, and circuit card
assemblies containing one or more of these sensitive electronic parts. [ESD Terms]
ELECTROSTATIC FIELD. The field of influence between two differently charged bodies.
ELECTROSTATIC METER MOVEMENT. A meter movement that uses the electrostatic repulsion of
two sets of charged plates (one fixed and the other movable). This meter movement reacts to voltage
rather than to current and is used to measure high voltage.
ELECTROSTATIC STRESS. The force exerted on an insulator by the voltage in a conductor.
