• Potentiometer pins and three pin wiring diagrams – Solution – Huaqiang Electronic Network

    Potentiometer pins and three pin wiring diagrams. Potentiometer (or fine-tuning resistance, etc.) Conventional pins (for example only, there are potentiometers of 3 pins), the resistance values ​​of the two heads are fixed, the intermediate pin is variable to any one end pin; It is equivalent to dividing the potentiometer from the intermediate pin into two series-connected resistors, and the series total resistance is fixed; therefore, if as the variable partial voltage resistance, one end is connected to the input voltage, the intermediate termination output, the remainder End ground; if the input voltage is used as a variable resistance, the input voltage is output, the remaining end can be floated, or connected to the intermediate end.

  • Resistance symbol – – Resistance symbols actually

    Guide: The resistance can be described as a variety of diversified, thousands of variable, can be divided into fixed resistance, variable resistance, special resistance, RT type carbon film resistance, RJ type metal film resistance, high power resistance, small power resistance, etc., resistance symbols One logo is also unique to each resistor. This article is to explain the resistance symbol in detail. It is said that the resistance symbol is strong, and only the article is also ~ 1. The reflection of the resistance, the symbol is R, the unit is ω (ohms), refers to the hindrance of the conductor to the current, is a conductor Inherent nature, will not disappear due to current

  • Davidan theorem summary

    Recall that Davidan equivalent circuit of any circuit is an equivalent voltage and an equivalent resistance series, TLV27L1IDBVR does not care what it is like the original circuit. The significance of Davidan Theorem is that it can be used in an equivalent circuit when the circuit takes an external load. Any load resistance connected to the Davidan equivalent circuit terminal has the same current and voltage when it is connected to the original circuit terminal. ;;; now give the steps to use Davidan theorem, outlined as follows: ;;; First step: Two terminals of Davidan equivalent circuit of the desired circuit
