Electrical Symbols — Semiconductor

Electrical Symbols — Semiconductor

Semiconductors are crystalline or amorphous solids with distinct electrical characteristics. They are of high resistance — higher than typical resistance materials, but still of much lower resistance than insulators. Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal. Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal. The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics. 26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram. Read more

Electrical Symbols — Composite Assemblies

Electronic components have two or more electrical terminals (or leads) aside from antennas which may only have one terminal. These leads connect to create an electronic circuit with a particular function (for example an amplifier, radio receiver, or oscillator). Basic electronic components may be packaged discretely, as arrays or networks of like components, or integrated inside of packages such as semiconductor integrated circuits, hybrid integrated circuits, or thick film devices. 26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram. Read more

Electrical Symbols, Electrical Diagram Symbols

When drawing Electrical Schematics, Electrical Circuit Diagrams, Power Systems Diagrams, Circuit and Wiring Diagrams, Digital and Analog Logic Schemes, you will obligatory need the electrical symbols and pictograms to represent various electrical and electronic devices, such as resistors, wires, transistors, inductors, batteries, switches, lamps, readouts, amplifiers, repeaters, relays, transmission paths, semiconductors, generators, and many more. Today these symbols are internationally standardized, so the diagrams designed using them are recognizable and comprehensible by specialists from different countries. Electrical Engineering Solution included to ConceptDraw Solution Park provides 26 libraries with 926 commonly used electrical schematic and electrical engineering symbols making the reality the easy drawing of Electrical diagrams, schematics and blueprints. Now you need only a few minutes to create great-looking Electrical diagram, simply choose required electrical design elements from the libraries, drag them on the needed places at the document and connect in a suitable way.

"In electronics, a vacuum tube, electron tube (in North America), tube, or thermionic valve or valve (in British English) is a device controlling electric current through a vacuum in a sealed container. The simplest vacuum tube, the diode, contains only two elements; current can only flow in one direction through the device between the two electrodes, as electrons emitted by the hot cathode travel through the tube and are collected by the anode. Addition of a third and additional electrodes allows the current flowing between cathode and anode to be controlled in various ways. The device can be used as an electronic amplifier, a rectifier, an electronically controlled switch, an oscillator, and for other purposes.
Vacuum tubes mostly rely on thermionic emission of electrons from a hot filament or a cathode heated by the filament. Some electron tube devices rely on the properties of a discharge through an ionized gas." [Vacuum tube. Wikipedia]
"The EL34 is a thermionic valve or vacuum tube of the power pentode type. It has an international octal base (indicated by the '3' in the part number) and is found mainly in the final output stages of audio amplification circuits and was designed to be suitable as a series regulator by virtue of its high permissible voltage between heater and cathode and other parameters. The American RETMA tube designation number for this tube is 6CA7. Russian analog is 6P27S (Cyrillic: 6П27C )" [EL34. Wikipedia]

Electrical Symbols — Stations

A power station is an industrial facility for the generation of electric power. Most power stations contain one or more generators, a rotating machine that converts mechanical power into electrical power. The relative motion between a magnetic field and a conductor creates an electrical current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Others use nuclear power, but there is an increasing use of cleaner renewable sources such as solar, wind, wave and hydroelectric. 26 libraries of the Electrical Engineering Solution of ConceptDraw PRO make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram. Read more

"In electronics, a diode is a two-terminal electronic component with asymmetric conductance; it has low (ideally zero) resistance to current in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes, a plate (anode) and a heated cathode. Semiconductor diodes were the first semiconductor electronic devices. ...
Today, most diodes are made of silicon, but other semiconductors such as selenium or germanium are sometimes used." [Diode. Wikipedia]
