A 1953 paper "Coding by Feedback Methods" [1] describes "decoding networks" that convert numbers (in any base) represented by voltage sources or current sources connected to resistor networks in a "shunt resistor decoding network" (which in base 2 corresponds to the binary-weighted configuration) or in a "ladder resistor decoding network" (which in base 2 corresponds to R–2R configuration ...
Variable resistor – a protective device that has a high resistance at low voltage but momentarily switches to lower resistance on exposure to a high voltage. vector control A strategy for control of variable-speed motor drives. vector group The classification of the connections of a polyphase transformer. vehicle-to-grid
In a series circuit, the current that flows through each of the components is the same, and the voltage across the circuit is the sum of the individual voltage drops across each component. [1] In a parallel circuit, the voltage across each of the components is the same, and the total current is the sum of the currents flowing through each ...
A Molex connector is a two-piece pin-and-socket interconnection which became an early electronic standard. Developed by Molex Connector Company in the late 1950s, the design features cylindrical spring-metal pins that fit into cylindrical spring-metal sockets, both held in a rectangular matrix in a nylon shell.
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
An axial-lead through-hole zero-ohm resistor is generally marked with a single black band, the symbol for "0" in the resistor color code. Surface-mount zero-ohm resistors are usually marked with a single or multiple "0" (if size allows marking), where the number of digits can indicate the tolerance or maximum resistance rating, as is the case ...
For resistances following the (E48 or) E96 series of preferred values, the former EIA-96 as well as IEC 60062:2016 define a special three-character marking code for resistors to be used on small parts. The code consists of two digits denoting one of the "positions" in the series of E96 values followed by a letter indicating the multiplier.
LEDs have also been used as a medium-quality voltage reference in electronic circuits. The forward voltage drop (about 1.7 V for a red LED or 1.2V for an infrared) can be used instead of a Zener diode in low-voltage regulators. Red LEDs have the flattest I/V curve above the knee.
