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 rocket engine in which the propellant is accelerated by some electric device.
2. A fence consisting of one or more lengths of wire energized with high-voltage, low-current pulses, and giving a warning shock when touched.
3. A wire fence carrying an electric current which gives a mild electric shock to any human or animal that touches it.
2. A region in space in which a stationary electric charge experiences a force due to its charge.
3. The area around an electrically charged body in which other charged bodies are acted on by an attracting or repelling force.
4. The lines of force exerted on charged ions in the bodily tissues by the electrodes that cause charged particles to move from one pole to another pole.
5. One of the fundamental fields in nature, causing a charged body to be attracted to or repelled by other charged bodies.
Associated with an electromagnetic wave or a changing magnetic field.
The electric field is stronger where the field lines are close together than where they are farther apart.
The value of the electric field has dimensions of force per unit charge and is measured in units of newtons per coulomb.
2. The effect of an electric field on spectrum lines.
The electric field may be externally applied; but in many cases it is an internal field caused by the presence of neighboring ions or atoms in a gas, liquid, or solid.
2. A network that transmits alternating currents of desired frequencies while substantially attenuating all other frequencies.
One side of the line is connected by an insulated wire to the primer, and the other side is grounded to the frame of the weapon.
2. The procedure used when applying electric energy to a semiconductor or other device to permanently modify its electrical characteristics.
2. Any furnace which by using the heating effect of an electric current, allows very high temperatures to be achieved.
A fuse commonly consists of a current-conducting strip or wire of easily fusible metal; whenever the circuit is made to carry a current larger than that for which it is intended, the strip melts to interrupt it.
In its most common form, a large number of conductors are mounted on an armature which is rotated in a magnetic field produced by field coils.2. A vacuum-tube oscillator or any other non-rotating device that generates an alternating voltage at a desired frequency when energized with direct-current power or low-frequency alternating-current power.
3. A circuit that generates a desired repetitive or non-repetitive waveform; such as, a pulse generator.
2. A guitar in which a contact microphone placed under the strings picks up the acoustic vibrations for amplification and for reproduction by a loudspeaker.
Volume and tone controls are usually also available.
