Electrical Symbols — Resistors

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. Resistors may be used to reduce current flow, and, at the same time, may act to lower voltage levels within circuits. In electronic circuits, resistors are used to limit current flow, to adjust signal levels, bias active elements, and terminate transmission lines among other uses. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.

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.

Wiring Diagrams with ConceptDraw DIAGRAM

A wiring diagram is a comprehensive diagram of each electrical circuit system showing all the connectors, wiring, terminal boards, signal connections (buses) between the devices and electrical or electronic components of the circuit. It also identifies the wires by wire numbers or colour coding. Wiring diagrams are necessary to troubleshoot and fix electrical or electronic circuits.

Mechanical Drawing Software

It is impossible to imagine mechanical engineering without drawings which represent various mechanical schemes and designs. ConceptDraw DIAGRAM diagramming and vector drawing software supplied with Mechanical Engineering solution from the Engineering area of ConceptDraw Solution Park offers the set of useful tools which make it a powerful Mechanical Drawing Software.
