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. The propulsion of spacecraft by using an electric arc or other electric heater to bring hydrogen gas or other propellant to the high temperature required for maximum thrust; for example, an arc-jet engine.
3. Vehicular propulsion which involves electrical heating to raise the energy level of the propellant.
In contrast, chemical rockets use the chemical energy of one or more propellants to heat and to accelerate the decomposition products (monopropellants) or combustion products (bipropellants) for thrusting purposes.
In both instances, the high-energy propellant gases are exhausted through a nozzle where they are accelerated to a high velocity, and thrust is produced by reaction.
2. A type of electrochemical recording, used in facsimile equipment, in which the chemical change is produced principally by signal-controlled thermal action.
2. An instrument which measures voltage and operates as an electrothermal ammeter, using a series resistor as a multiplier.
Examples include the thermocouple, bolometric (a tool that detects and measures small amounts of thermal radiation), hot-wire, and hot-strip instruments.
2. Electroplating an objecvt with tin.
2. The modified condition of a motor nerve under the influence of a constant galvanic current.
