A 20K potentiometer is a type of variable resistor used extensively in electronic circuits to adjust resistance values and control electrical parameters. It typically features a resistive element in the form of a track made from carbon or conductive plastic. The potentiometer has three terminals: two fixed terminals and one adjustable terminal (the wiper). The wiper slides across the resistive track as the knob or slider is turned, thereby varying the resistance between the wiper and the fixed terminals. This allows for precise control over voltage, current, and signal strength in a circuit.
The 20K refers to the total resistance value that the potentiometer can achieve when the wiper is set at its maximum resistance setting, which is 20,000 ohms. Potentiometers are available in various forms, such as rotary (knob-controlled) and linear (slider-controlled).
Features:
- Adjustable resistance (0 to 20,000 ohms)
- Three terminals: Two fixed and one adjustable (wiper)
- Manual control (via knob or slider)
- Compact size
- Durable and reliable
- Linear or logarithmic adjustment options
Application:
- Used in electronics for controlling voltage, current, signal strength, and other parameters in devices like volume controls, dimmer switches, and tuning circuits.
