Adjustable resistance effect

The adjustable resistor is a resistor whose resistance value can be adjusted. For occasions where the circuit current needs to be adjusted or the circuit resistance needs to be changed, the adjustable resistor can change the characteristics of the signal generator, dim the lights, start the motor or control its speed, mainly by changing its own resistance and controlling the series circuit The current in the circuit can protect some electrical components.

Description of Types and Structural Characteristics of Adjustable Resistors

The adjustable resistor is generally composed of a resistor body and a rolling or sliding system. Its operating principle and potentiometer operating principle are roughly the same. When a voltage is applied between the two fixed electric contacts of the resistor body, the orientation of the contact on the resistor body is changed by rolling or sliding system, and a voltage that is necessarily related to the position of the moving contact can be obtained between the moving contact and the fixed contact.

Potentiometer use matters needing attention

The resistance of the wire wound potentiometer is mainly made of poly carbonate synthetic resin. It should avoid contact with ammonia, other amines, alkali aqueous solution, aromatic hydrocarbons, ketones, aliphatic hydrocarbons, and fortifiers (high pH value), otherwise it will affect its performance.

Adjustable resistance must pay attention to 6 matters!

Adjustable resistance is also called variable resistance, which is Rheostat in English. Adjustable resistance is a kind of resistance. The resistance value of adjustable resistance can be adjusted artificially to meet the needs of the circuit. Adjustable resistors can be divided into many different models and types according to the size of the resistance value, the range of adjustment, the form of adjustment, the production process, the production material, the volume size, etc., which can be divided into: adjustable resistors for electronic components, adjustable resistors for porcelain plates, patch adjustable resistors, wire wound adjustable resistors, etc.
