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.
One voltage is that which appears across the load, and the other is obtained across a resistor in the series with the line.
2. The energy required to raise an electron with the Fermi energy (average energy of electrons in a metal) in a solid to the energy level of an inactive electron in a vacuum outside the solid.
The term Fermi energy is named after Enrico Fermi (1901-1954), an Italian nuclear physicist and refers to the level in the distribution of electron energies in a solid at which a quantum state is equally likely to be occupied or empty.
2. An airborne radar that uses a phased-array antenna which changes radar-beam forms and beam positions at electronic speeds.
When combined with digital processing of the radar returns, it can simultaneously provide such functions as beacon-locating, forward-looking mapping, navigation updating, terrain avoidance, and terrain-following in manned strategic bombers and other aircraft.
2. The science of all systems involving the use of electrical instruments used for communication information processing, and control.
3. That field of science and engineering which deals with electron systems, circuits, and devices that control the flow of electrons.
4.The name given to that branch of electrical engineering that deals with tools the operations of which depend on the movement of electrons in space as opposed to the movement of electrons in liquids or solid conductors; for example, radio tubes, photoelectric cells, etc.
The term electronics refers to a large number of different phenomena and devices in which useful electrical effects are achieved through control of the motion of electrons.
The fact that the time in which we live is sometimes referred to as "the electronic age" indicates what widespread consequences are involved.
A representative partial list of electronic devices today includes such diverse applications as rectifiers, amplifiers, integrated circuits, memories, microwave sources and receivers, light-emitting devices, light-detecting devices, and solar cells to convert solar energy into electricity.
