Resistor Color Code Rechner — Formel

Resistor Color Codes

4-Band System

  • Band 1: First digit
  • Band 2: Second digit
  • Band 3: Multiplier (10^x)
  • Band 4: Tolerance

    • Black=0, Brown=1, Red=2, Orange=3, Yellow=4, Green=5, Blue=6, Violet=7, Grey=8, White=9

    Lösungsbeispiel

    Yellow(4), Violet(7), Red(x100).

    1. Base = 4 x 10 + 7 = 47
    2. Multiplier = 10^2 = 100
    3. Resistance = 47 x 100 = 4700 ohms = 4.7k
