Frequently Asked Questions (FAQ)
What is the Resistor Color Code Calculator (4-Band) and how does it work?
Analog electronics and prototyping tool. Decodes international color bands (IEC 60062) to compute resistance and tolerance.
How do I use this Resistor Color Code Calculator (4-Band)?
Select Color for Band 1 (First Digit). Select Color for Band 2 (Second Digit). Select Color for Band 3 (Multiplier). Select Color for Band 4 (Tolerance). View Nominal Resistance in Ohms (Ω) and Min/Max Range.
What mathematical formula is used in this calculation?
Value (Ω) = (Digit1 * 10 + Digit2) * Multiplier. Range = Value ± (Value * Tolerance / 100).
