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 end of a line where signals are either transmitted or received, or a point along the length of a line where the signals are made available to an apparatus: Randy, the fired train conductor, attempted to disrupt the electric terminals at the railroad station so the trains could not run on time.
A thermocouple is a thermoelectric device used to measure temperatures accurately, especially one consisting of two dissimilar metals joined so that a potential difference generated between the points of contact is a measure of the temperature difference between the points.
One junction is at the temperature to be measured, the second is at a fixed temperature. The electromotive force generated depends upon the temperature difference.
Electricity is also used in the movement of vehicles in other ways, but these forms are not usually included in the category of electric traction; examples include, battery-powered electric automobiles, battery-propelled vans for city delivery or warehouse use, and modern diesel-electric locomotives in which the wheels are driven by electric motors powered by diesel engines.
Vehicle-type alarm systems can usually detect electric transients in such activities, as starting the engine or opening a door, which can initiate a courtesy light that indicates a disturbance in the circuit that can result in making a warning alert.
2. The process of selecting a desired frequency on a component; such as, a receiver, a transmitter, or an oscillator, without using mechanical devices.
Three different systems of electric units are used:
- The electromagnetic unit.
- The electrostatic unit.
- The ordinary or practical units.
The commonly used practical units are the ampere or unit of current, the volt or unit of electromotive force, the ohm or unit of resistance, the coulomb or unit of quantity, the farad or unit of capacitance, and the watt or unit of power.
2. The force on a stationary positive electrical charge per unit charge at a point in an electric field.
It is usually measured in volts per meter.
2. Any ground vehicle whose original source of energy is electric power; such as, an electric car or an electric locomotive.
2. A system of electric conductors and components for conveying electric power from a source to the point of use.
In general, electric wiring for light and power must convey energy safely and reliably with low power losses, and must deliver it to the point of use in an adequate quantity at a rated voltage.
Electric wiring systems are designed to provide a constant voltage to the load within the capacity limits of the system.
