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.

Electrical Symbols — Power Sources

A voltage source is a two terminal device which can maintain a fixed voltage. An ideal voltage source can maintain the fixed voltage independent of the load resistance or the output current. However, a real-world voltage source cannot supply unlimited current. A voltage source is the dual of a current source. Real-world sources of electrical energy, such as batteries, generators, and power systems, can be modeled for analysis purposes as a combination of an ideal voltage source and additional combinations of impedance elements. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM 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.

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 DIAGRAM 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.
The vector stencils library "Power sources" contains 9 element symbols of power sources and batteries for drawing the electrical schematics and electronic circuit diagrams.
"A power supply is a device that supplies electric power to an electrical load. The term is most commonly applied to electric power converters that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (mechanical, chemical, solar) to electrical energy. A regulated power supply is one that controls the output voltage or current to a specific value; the controlled value is held nearly constant despite variations in either load current or the voltage supplied by the power supply's energy source.
Every power supply must obtain the energy it supplies to its load, as well as any energy it consumes while performing that task, from an energy source. Depending on its design, a power supply may obtain energy from:
(1) Electrical energy transmission systems. Common examples of this include power supplies that convert AC line voltage to DC voltage.
(2) Energy storage devices such as batteries and fuel cells.
(3) Electromechanical systems such as generators and alternators.
(4) Solar power." [Power supply. Wikipedia]
The shapes example "Design elements - Power sources" was drawn using the ConceptDraw PRO diagramming and vector drawing software extended with the Electrical Engineering solution from the Engineering area of ConceptDraw Solution Park.

Electrical Symbols, Electrical Schematic Symbols

Electrical Schematics and Electrical Circuit Diagrams are included to the number of obligatory diagrams and documents while developing the package of construction documentation for the building project. It is comfortable to use the special drawing software for designing diagrams of this type. ConceptDraw DIAGRAM diagramming and vector drawing software extended with Electrical Engineering solution from Industrial Engineering Area of ConceptDraw Solution Park provides the powerful drawing tools, a lot of specific samples and templates, and numerous libraries with incredibly large quantity of predesigned electrical schematic symbols, including analog and digital logic electrical symbols, electrical circuits symbols, inductors, power sources, lamps, resistors, transistors, delay elements, switches and relays, terminals and connectors, and many other useful electrical symbols, which will be helpful for easy designing professional looking Electrical Schematics, Electrical Engineering Diagrams, Circuit and Wiring Diagrams, Power Systems Diagrams, Digital and Analog Logic Schematics.

Cisco Products Additional. Cisco icons, shapes, stencils and symbols

The ConceptDraw vector stencils library Cisco Products Additional contains equipment symbols for drawing the computer network diagrams.
The vector stencils library "Resources and energy" contains 19 clipart images for drawing illustrations on resources and energy.
"Natural resources occur naturally within environments that exist relatively undisturbed by humanity, in a natural form. A natural resource is often characterized by amounts of biodiversity and geodiversity existent in various ecosystems.
Natural resources are derived from the environment. Some of them are essential for our survival while most are used for satisfying our wants. Natural resources may be further classified in different ways.
Natural resources are materials and components (something that can be used) that can be found within the environment. Every man-made product is composed of natural resources (at its fundamental level). A natural resource may exist as a separate entity such as fresh water, and air, as well as a living organism such as a fish, or it may exist in an alternate form which must be processed to obtain the resource such as metal ores, oil, and most forms of energy." [Natural resource. Wikipedia]
The clip art example "Resources and energy - Vector stencils library" was created in ConceptDraw PRO diagramming and vector drawing software using the Manufacturing and Maintenance solution from the Illustration area of ConceptDraw Solution Park.
