Resistor Color Code Rechner
Decode 4-band resistor color codes to find resistance in ohms und kilohms.
Widerstand
4,700 Ω
Resistance (k)4.700 kΩ
Resistance vs Band 1 Digit (0-9)
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).
- 01Base = 4 x 10 + 7 = 47
- 02Multiplier = 10^2 = 100
- 03Resistance = 47 x 100 = 4700 ohms = 4.7k
Häufig Gestellte Fragen
How do I identify band 1?
Band 1 is closest to one end. The tolerance band (gold/silver) is at the opposite end.
5-band resistors?
Add a third significant digit before the multiplier for more precision.
Gold/silver multiplier?
Gold = x0.1, Silver = x0.01 for sub-10 ohm resistors.
