An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may vary from country to country, or engineering ...
A less common symbol is simply a series of peaks on one side of the line representing the conductor, rather than back-and-forth. Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle ...
This beam is specified for use whenever other vehicles are present ahead. UN ECE regulations for dipped beam headlights specify a beam with a sharp, asymmetric cut-off; the half of the beam closest to oncoming drivers is flat and low, while the half of the beam closest to the outside of the road slopes up and towards the near side of the ...
Reference should be made to codes and standards. For example, IEC 60027, and Letter Symbols in Electrical Technology. Here are tables of widely accepted symbols. They are meant to be a guideline: Using the same symbols for the same things in different articles will increase their consistency, making them easier to understand and to improve.
An instrument that provides highly magnified images by use of an electron beam. electronic amplifier A device that increases the power of an electrical signal by electronic means. electronic circuit A circuit using one or more electronic devices. electronic component An active or passive element of an electronic circuit. electronic control unit
In a radio antennas, the main lobe or main beam is the region of the radiation pattern containing the highest power or exhibiting the greatest field strength.. The radiation pattern of most antennas shows a pattern of "lobes" at various directions, where the radiated signal strength reaches a local maximum, separated by "nulls", at which the radiation falls to zero.
It is numbered with a stylized flag symbol surrounding the number (or sometimes a delta symbol). A general note applies generally and is not called out with flags. 2. Find number: "FN" meaning "find number" refers to the ordinal number that gives an ID tag to one of the constituents in a parts list (list of materials, bill of materials).
Low beam (dipped beam, passing beam, meeting beam) headlamps provide a distribution of light designed to provide forward and lateral illumination, with limits on light directed towards the eyes of other road users to control glare. This beam is intended for use whenever other vehicles are present ahead, whether oncoming or being overtaken.
