Resistor colour code
Read the value and tolerance of 4- and 5-band resistors.
Resistance
47 kΩ
Tolerance
± 5 %
Range
44.65 kΩ – 49.35 kΩ
Read from the end with the bands closest together. Tolerance bands (gold, silver, brown) usually sit slightly apart from the others.
How it works
Through-hole resistors are marked with coloured bands for the digits, a multiplier and the tolerance.
Formulas
- R = digits × multiplier
