10K Ohm Potentiometer

10K Ohm Potentiometer is an adjustable or Variable resistor PCB mountable and has 3 terminals. The voltage between the terminal varies as the preset is rotated. The Variable resistors are used for variation voltage as per the need in a circuit.

10K Ohm Potentiometer is used for adjusting various parameters like voltage, current, resistance, etc. in an electronic circuit.

Specifications of 10K Ohm Potentiometer

• Resistance: 10 kOhm
• Shaft Diameter: 6 mm
• Shaft Length: 15 mm
• Tolerance: 20%
• Color and size might vary.

A 10k ohm potentiometer is a type of variable resistor used to control electrical parameters such as voltage or current in a circuit. It consists of three terminals:

1. Two fixed terminals connected to a resistive element (usually a resistive track), and
2. One adjustable terminal (called the wiper) moves across the resistive track when you turn the potentiometer knob or adjust it in another way.

Key Features of 10K Ohm Potentiometer:

• Resistance Value: The total resistance between the two fixed terminals is 10,000 ohms (10k ohms). This value determines how much the potentiometer can restrict current flow in a circuit.
• Adjustable Resistance: By rotating the knob or slider, the wiper moves along the resistive track, which changes the resistance between the wiper terminal and the other two terminals, allowing for fine control over the voltage or current.
• Applications:
  • Volume Control in audio devices (adjusting sound levels).
  • Brightness Adjustment in light dimmers.
  • Position sensing (e.g., in joysticks or control panels).

How it Works:

• When the potentiometer’s wiper is moved, the resistance between the wiper and one terminal changes, allowing you to adjust the output signal (e.g., voltage) accordingly.
• In a voltage divider configuration, the output voltage can be adjusted by turning the potentiometer.

Example Circuit:

For a simple voltage divider:

• You connect the two fixed terminals to a power source (e.g., 5V) and ground.
• The wiper is connected to the input of another circuit, and adjusting the potentiometer changes the voltage at the wiper.

Why 10k Ohms?

A 10k ohm potentiometer is commonly used because it strikes a balance between power consumption and sensitivity. It’s widely compatible with many electronic components and suitable for various general-purpose applications.
