Enter the 3-digit code printed on your potentiometer
Resistance Value
100kΩ
10 × 10⁴ = 100,000Ω
Significant Figures: 10, Multiplier: 10^4
How to Read Potentiometer Codes:
- 3-Digit Code: [First][Second][Multiplier]
- First Two Digits: Significant figures of resistance
- Third Digit: Multiplier (power of 10)
- Example 104: 10 × 10⁴ = 100,000Ω = 100kΩ
- Example 503: 50 × 10³ = 50,000Ω = 50kΩ
