Potentiometer (English: Potentiometer) is a variable resistor. Usually by a resistor and rotating or sliding components, namely by a movable contact on the resistor body movement, partial voltage output.
Potentiometer role - regulated voltage (including DC voltage and signal voltage) and current size.
The structural characteristics of the potentiometer - potentiometer resistor has two fixed ends, or by manually adjusting shaft slip handle and change the position of the movable contact on the resistor, the change between the movable contact with either a fixed end resistance value, thus changing the magnitude of the voltage and current.
An electronic component potentiometer is adjustable. It is composed of a resistor and a rotating or sliding system. When a voltage is applied between the two fixed contacts resistor, the system changes by rotating or sliding contact position on the resistor between the movable contact and the fixed contact can be obtained with a movable contact position a voltage of a certain relationship. It is mostly used as a voltage divider, then the potentiometer is a four-terminal device. Potentiometer is basically a sliding rheostat, there are several styles, generally used in the speaker volume switch and the power of the laser head size adjustment potentiometer is an adjustable electronic components.
For dividing a variable resistor. The resistance of the exposed body, pressed against one or two movable metal contacts. Contact position determining resistor and end any resistance between contacts. By material wound, carbon film, solid core potentiometer; output and input voltage ratio according to the rotation angle of the relationship between sub-linear potentiometer (linear) function potentiometer (curvilinear). The main parameters of resistance, tolerance, rated power. Widely used in electronic equipment, for use in the audio volume control and receiver.
