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.

electrically
By means of electricity; as, electrically controlled lights.
electrically active fluid
A fluid in which the properties are altered by either an electric field (electrorheological fluid) or a magnetic field (ferrofluid).
electrically alterable read-only memory (s), EAROM (noun)
1. A read-only memory in which selected locations can be reprogrammed for a limited number of times by the application of an electric field; used on IBM computers.
2. A read-only memory which can be reprogrammed electrically in the electric field for a limited number of times, after the entire memory is erased by applying an appropriate electric field.
3. A kind of non-volatile memory used in computers and other electronic devices in order to store small amounts of data that must be saved when the electric power is removed; for example, calibration tables or device configurations.
electrically connected
1. Joined through an electrical conducting path; such as, a resistor, an inductor, a capacitor, or a wire.
2. Electricity which is connected by means of a conducting path, or through a capacitor that is distinguished from a connection simply through electromagnetic induction.
electrically erasable programmable read-only memory, EEPROM
1. A method of storing data on microchips.

Usually bytes can be erased and reprogrammed individually.

RFID tags that use EEPROM are more expensive than factory programmed tags, where the number is written into the silicon when the chip is made, but they offer more flexibility because the end user can write an ID number to the tag at the time the tag is going to be used.

2. A form of read-only memory which can be electrically erased and reprogrammed.
3. An integrated-circuit memory chip that has an internal switch to permit a user to erase the contents of the chip and to write new contents into it with electrical signals.
electrically erasable read-only memory, EEROM
A form of read-only memory in which the entire contents can be erased electrically and reprogrammed hundreds of time without damaging the device.
electrically stimulated osteogenesis
A bone regeneration process in which surgically implanted electrodes convey electric current, particularly at nonunion fracture sites; effective because of the different electrical potentials within bone tissue.

The process is effective because of the different electric potentials within bone tissue. Viable non-stressed bone is electronegative in the metaphysical regions and over a fracture callus and electropositive in the diaphyses and other less active regions.

Electric stimulation of the fractures can accelerate osteogenesis, forming bone more quickly in the area of a surgically inserted negative electrode.

Electrically stimulated osteogenesis can be achieved with a device that stimulates the fracture site electrically by means of several surgically implanted cathodes.

Another method for applying electrical current to fractured bone involves an open surgical procedure and implantation of electrodes.

electrically suspended gyro
1. A gyroscope characterized by a central rotating element which is maintained in place by an electromagnetic or electrostatic field.
2. A gyroscope in which the main rotating element is suspended by an electromagnetic or an electrostatic field.
electrically tuned oscillator
An oscillator whose frequency is determined by the value of a voltage, current, or power.

An oscillaory is a mechanical or electronic device that produces a back-and-forth periodic motion.

A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air resistance or friction.

In electronic oscillators, electrons oscillate with a constant period and also require the addition of energy to replace energy loss.

Electronic oscillators are used to generate alternating current and high-frequency currents for carrier waves in radio broadcasting.

electrically variable coil (s) (noun), electrically variable coils (pl)
An iron-core coil whose inductance can be varied or modified over a wide range by changing a small DC control current.
electric-arc welding, electric arc welding
1. A welding process which uses an electric arc as the source of heat.
2. Welding in which the joint is heated to fusion by an electric arc or by a large electric current.
3. The joining of metal components by fusing them with heat from an electrical arc struck between two electrodes.
electric-discharge machining
A metal-cutting process in which high-frequency discharges from a negatively charged metal tool remove metal from the work piece by electroerosion.

There is no electrolyte, but the work is submerged in oil to flush away eroded particles and to delay each spark until peak energy is built up.>

electrician
1. A skilled person whose trade is making, installing, maintaining, or repairing electrical equipment, wiring, and electric devices; such as, lights, motors, etc.
2. A technician who specializes and who is licensed to install, to maintain, to repair, or to approve electrical wiring or electrical devices and who is capable of operating electrical equipment.
electricians (lexicomedy)
1. An ohm of electricians.
2. A jolt of electricians.
electricity
1. A fundamental form of energy, consisting of oppositely charged electrons and protons that produce light, heat, magnetic force, and chemical changes; as well as, the flow of this energy or electric current.
2. The separation or movement of electrons and protons; either the separation of charges by friction, static electricity, or the movement of charges caused by magnetism and chemical batteries, current flow.
3. A form of energy expressed by the activity of electrons and other subatomic particles in motion, as in dynamic electricity, or at rest, as in static electricity.

Electricity may be negative, when there is a surplus of electrons, or positive, when there is a surplus of protons or a deficiency of electrons.

4. A fundamental quantity in nature which is at rest and has an electric field that possesses potential energy and which can exact force.

Electricity in motion (an electric current) has both electric and magnetic fields which possess potential energy and can exert force.
