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 traumatic physical state caused by the passage of electric currents through the body.
3. The sudden pain, convulsion, unconsciousness, or death produced by the passage of electric current through a body.
4. Injury from electricity that varies according to the type and strength of current and length and location of the contacts.
It usually involves an accidental contact with exposed parts of electric circuits in home appliances and domestic power supplies; however, it may also result from lightning or contact with high-voltage wires.
Electric shocks range from trivial burns to complete charring and destruction of skin. They may also cause unconsciousness from paralysis of the respiratory center, fibrillation of the heart, or both depending on the intensity of the electric current, the type of current, and the duration and the frequency of the current flow.
Alternating current (AC), direct current (DC), and mixed currents cause different kinds and different degrees of damage to the body.
Burns and the loss of consciousness are a couple of the symptoms of electrical injury.
A capacitor bank charged to a high voltage is discharged into the gas at one tube end to ionize and heat the gas, producing a shock wave that may be studied as it travels down the tube.
2. A precision low-value resistor placed across the terminals of an ammeter to increase its range by allowing a known fraction of the electric-circuit current to go around the meter.
2. A device made of a long wire which has been wound around many times into a tightly packed coil.
It has the shape of a long cylinder and if a current is sent through a solenoid made of insulated wire and having a length much greater than its diameter, a uniform magnetic field will be created inside the solenoid.
This field can be intensified by inserting a ferromagnetic core into the solenoid.
Electric sparks play an important part in many physical effects; usually these are harmful and undesirable effects, ranging from the gradual destruction of contacts in a conventional electrical switch to the large-scale disruption resulting from lightning discharges.
Sometimes the spark is useful; for example, its function in the ignition system of an automobile, its use as an intense short-duration illumination source in high-speed photography, and its use as a source of excitation in spectroscopy.
The portable battery-powered machine does not correct scoliosis (abnormal lateral curvature of the spine); however, it apparently does keep it from getting worse.
A stacker is a machine for lifting merchandise on a platform or fork and arranging it in tiers; operated by hand, electric, or hydraulic mechanisms.
One of the most effective means for accomplishing this action is a gaseous tube energized by the discharge of an electrical condenser.
Flashes as short as one microsecond have been produced in this procedure.
It has a thermocouple, resistance wire, or thermistor as the temperature-sensitive element.
