100k Ohm Potentiometer
= Versatile Variable Resistor for Analog Control and Adjustment =
A 100k potentiometer is a three-terminal variable resistor that allows you to manually adjust resistance values in a circuit. It is widely used for volume control, sensor calibration, and user input in Arduino and electronics projects.
Adjustable Resistance - Provides variable resistance from 0 to 100,000 ohms for analog control
Multiple Applications - Works for audio control, tuning circuits, and user interfaces
Typical power rating is 100mW with resistance tolerance of ±20%
Choose between linear taper (smooth adjustment) or audio taper (logarithmic for volume)
Never exceed the power rating to prevent overheating and damage
