Potentiometer Carbon 100 Ohm

The Potentiometer Carbon 100 Ohm is a variable resistor with a carbon resistive track and a total resistance of 100 Ω. It has three terminals: the two ends of the track and a wiper that moves along it, so you can use it as an adjustable voltage divider or, with two terminals, as an adjustable resistor. The low 100 Ω value suits circuits that need small resistance changes at low impedance.

Potentiometer Carbon 100 Ohm Specifications

• Total resistance: 100 Ω
• Track material: carbon
• Terminals: 3 (two track ends and the wiper)
• Use: voltage divider (all 3 terminals) or variable resistor (wiper and one end)

Potentiometer Carbon 100 Ohm Applications

• Fine adjustment and trimming in low-resistance circuits
• Setting current in test and bench circuits
• Low-impedance voltage dividers and calibration
• Electronics classes on resistance and Ohm's law

What's in the Box

• 1 × 100 Ω carbon potentiometer

Tip: A 100 Ω potentiometer connected across 5 V draws 50 mA and dissipates 0.25 W, which can overheat small carbon potentiometers. To read a knob on an Arduino analog pin, a 10 kΩ potentiometer is the usual choice.
