Working
A 100k potentiometer is a variable resistor that allows precise control of resistance in an electronic circuit. By turning the knob or sliding the lever, you adjust the contact point on the resistive material, varying the output voltage. This makes it suitable for high-impedance applications.
Applications
- Adjusting contrast in LCD displays.
- Fine-tuning circuits in high-impedance systems.
- Setting reference voltages for operational amplifiers.
- Audio equipment for gain and tone control.
- Precision voltage dividers in electronic devices.
Pinout
The 100k potentiometer has three pins:
- Pin 1: Connects to the positive voltage supply (VCC).
- Pin 2: The wiper or output pin, providing adjustable voltage.
- Pin 3: Connects to ground (GND).
