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 lamp in which light is produced by an electric discharge between electrodes in a gas (or vapor) at low or high pressure.
3. A lamp that uses the transmission of an electric current through a gas or vapor to produce illumination. Neon, mercury and argon lamps are examples of electric-discharge lamps.
4. A lamp whose light is produced by current flow through a gas or vapor in a sealed glass enclosure.
Examples of these lamps include argon glow, mercury-vapor, neon glow, and sodium-vapor.
2. The flow of electricity through a gas, resulting in the emission of radiation that is characteristic of the gas and of the intensity of the current.
3. The removal of a charge from a battery, capacitor, or other electric-energy storage device.
4. The passage of electricity through a gas, usually accompanied by a glow, arc, spark, or corona.
It is primarily used where precise control is not required; such as, for removing broken drills and taps.
It is made up of ions of one charge type which are fixed to the surface of the solid and an equal number of mobile ions of the opposite charge which are distributed through the neighboring region of the liquid.2. The area of a charge separation formed when an electrode meets an ionic conductor.
A metal electrode in a water solution forms a specific structure consisting of the metal surface itself, an adjoining layer of adsorbed (adhesion to the surfaces of solids) water molecules and ions, and an outer region of oppositely charged ions diffused in the liquid.
This causes an electric field of considerable intensity.3. An interfacial region, near the boundary between two different phases of a substance, in which physical properties change significantly.
4. A structure that appears on the surface of a charged object when it is placed into a liquid.
This object might be a solid particle, a gas bubble, a liquid droplet, or a porous body.
This includes a magnet or a polar molecule; more precisely, it is the limit as either charge goes to infinity, the separation distance to zero, while the product remains constant.
2. A mechanism that transmits motion from one shaft to another and controls the velocity ratio of the shafts by electrical means.
3. An automatic transmission in which a generator, connected with the engine, supplies power to a separate electric motor or motors; which drive the wheels.
It is used in buses, trucks, and Diesel locomotives.
Found in South American Amazon and Orinoco rivers and tributaries. They produce powerful electric shocks to stun prey, or for defense, sufficient to immobilize a large mammal.
2. The energy constituent in a circuit because of its position in relation to a magnetic field.
3. The energy of electric charges or currents because of their positions in an electric field.
4. The integral with respect to time of the instantaneous power input or power output of a circuit or appliance.
The basic unit is the watthour.
