Colour coding of Resistance
The carbon resistance has normally four coloured rings bands $A, B, C$ and $D$.
Colour bands A and B Indicates the decimal figure.
Colour band C Indicates the decimal multiplier.
Colour band D Indicates the tolerance in per cent about the indicated value. Tolerance represents the percentage accuracy of the indicated value.
