Yellow = 4

Orange = 3

Red = 100

None = 20%

## Calculate ohms:

Ohms = (Band1 & Band 2) x Band 3 Multiplier
Ohms = 43 x 100

### How does the Resistor Color Codes Calculator work?

Free Resistor Color Codes Calculator - Given 3 Band level color codes and a tolerance color chosen, this calculates the resistance in ohms and the tolerance percentage
