Red, red, brown is a 220 ohm, 20% resistorīrown, black, orange is a 10k, 20% resistor They will be calculated using the 4 band rule (digit, digit, multiplier). You don't have to enter the 4th band, as 20% resistors don't have a tolerance ring. Resistors with 6 bands are basically 5-band resistors with an additional ring indicating the reliability or the temperature coefficient.

How can I calculate its value?Įnter the first five colors.
