English: American-style resistor (a), rheostat (variable resistor) (b), and potentiometer (c) electrical schematic symbols. Date: 4 December 2011: Source: Own work:
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 ...
The word rheostat was coined in 1843 by Sir Charles Wheatstone, [7] from the Greek ῥέος rheos meaning "stream", and - στάτης-states (from ἱστάναι histanai, "to set, to cause to stand") meaning "setter, regulating device", [8] [9] [10] which is a two-terminal variable resistor. For low-power applications (less than about 1 ...
voltage regulators are often "U" for IC, pots and trimmers often "R" for resistor X: Socket connector for another item not P or J, paired with the letter symbol for that item (XV for vacuum tube socket, XF for fuse holder, XA for printed circuit assembly connector, XU for integrated circuit connector, XDS for light socket, etc.) X, XTAL, Y
The L pad attenuates the signal by having two separate rheostats connected in an "L" configuration (hence the name). One rheostat is connected in series with the loudspeaker and, as the resistance of this rheostat increases, less power is coupled into the loudspeaker and the loudness of sound produced by the loudspeaker decreases.
The internationally standardized symbol for a resistor is therefore now simplified to an oblong, sometimes with the value in ohms written inside, instead of the zig-zag symbol. 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.
Modern varistor schematic symbol, which is the same as a thermistor symbol [1] A varistor (a.k.a. voltage-dependent resistor (VDR)) is a surge protecting electronic component with an electrical resistance that varies with the applied voltage. [2] It has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode ...
A: preset resistor, B: preset resistor (alternate), C: preset potentiometer, D preset potentiometer (alternate), E: preset inductor, F: preset capacitor. In circuit diagrams, the symbol for a variable component is the symbol for a fixed component with a diagonal line through it terminating in an arrow head.
