The first three bands give the value of the resistor in ohms [0].
The fourth band is an accuracy rating %. Most expensive and most accurate = RED. Medium expensive and accurate = GOLD. Least expensive and accurante = SILVER.
RED – the resistor is within 2% of the coded accuracy value. GOLD – the resistor is within 5%. SILVER – the resistor is within 10%.
