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. Scanning in which an electron beam, controlled by electric or magnetic fields, is swept over the area under examination, in contrast to mechanical or electromechanical scanning.
3. In telecommunications, the technique of scanning a surface to reproduce or to transmit a picture.
4. In facsimile, a method of scanning in which the motion of the scanning spot is completely controlled by electronic procedures.
2. An infrequent disturbance of the electric field in the lower atmosphere caused by strong winds and the blowing of dust, but without thunderstorm activity.
3. Any meteorological disturbance in which the air is highly charged with electricity, occurring in fine weather, without clouds or rain, and often accompanied by dry, dusty winds.
4. A sudden change in the pattern of earth currents, causing interference with radio reception.
5. A meteorological condition marked by an intense electric field within a cloud or clouds.
2. The electronic symbol is a pictogram that is used to represent the various electrical and electronic devices; such as, batteries, wires, resistors, and transistors as shown in a schematic diagram of an electrical or electronic circuit.
2. All of the conductors and electricity that use devices which are connected to a source of electromotive force or generator.
3. The equipment in a motor vehicle that provides electricity to start the engine and to ignite the fuel, to operate the lights, the windshield wipers, the heater, the air conditioner, and the radio.
It is used to cover joints in insulated wires or cables.
2. A thermometer that uses thermoelectric current to measure temperature.
3. An instrument which utilizes an electrical means to measure temperature; such as, a thermocouple or resistance thermometer.
4. A thermometer indicating temperature variations by means of electrical current flowing through a circuit in which a galvanometer is inserted.
The sensitive element can be an electrical resistance whose value changes with temperature, or a thermocouple (formed by two soldered metals), which also generates specific quantities of current at different temperatures.
2. The vertical measure between the surface of an ocean current and an isokinetic point having a value of about one-tenth the surface speed.
2. A radio broadcast from a phonograph record or the phonograph record itself.
3. A radio program broadcast from a special phonograph record or tape recording or the recording itself.
When radio stations first started to record programs, they recorded on "electrical transcription disks".
2. A standard reference position from which rotor angles are measured in synchros and other rotating instruments.
Synchros consist of several devices which are used for transmitting and receiving angular positions or angular motions over wires; such as, synchro transmitters or synchro receivers.
