electro-, electr-, electri-
(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)
Electronics in our lives consists of numerous tools
Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.
2. A device that measures voltage in amplifier-rectifier circuits.
The most common type is an aneroid barometer calibrated to show the drop in atmospheric pressure in terms of linear elevation as an airplane, balloon, or mountain climber rises.
It shows height above sea level, but not above such land features as hills, mountains, and valleys.
The radio altimeter, or terrain-clearance indicator, is an absolute altimeter which indicates the actual altitude over water or over terrain, regardless of how uneven it is.
It functions by first sending either continuous or pulse radio signals from a transmitter in an aircraft to the earth's surface.
2. The total angular momentum associated with the orbital motion of the spins of all the electrons of an atom.
When someone passes a gate, or door, of a place holding an item with an electronic article surveillance that hasn't been turned off, an alarm sounds.
The term omnirange refers to a radio aid to navigation which provides a direct indication of the magnetic bearing (omnibearing) of that station from any direction.
2. On an airborne radar plan position indicator (PPI) a bright rotatable radial line used for determining the bearing of an aircraft.
2. A weighing balance which uses forces produced by known currents to balance unknown currents and, so make unknown weights come to within parts of a microgram.
2. Bands of spectral lines connected with a change of electronic state of a molecule.
Each band is corresponding to vibrational energies in the initial and final conditions and each band consists of numerous rotational lines.
2. A stream of electrons, emitted by a single source, which move in the same direction, and at the same speed.
3. A stream of electrons which can "write" on phosphor surfaces; such as, a CRT screen expose photoresistent-coated semiconductor wafers by direct writing or exposure through a mask, or magnify objects by passing through magnetic "lenses".
It can also be a cutting tool.
A cathode-ray tube, or CRT, produces images when its phosphorescent surface is struck by electron beams.
2. A reference to a marine radar set, the bright rotatable radial line on the plan position indicator that is used for the determination of bearing or the calculation of a direction or a geographic position.
