The below equation shows the method to find the resistance:
Resistor Colour Coding uses colored bands to easily identify a resistor resistive value and its percentage tolerance. The resistor color code markings are always read one band at a time starting from the left to the right, with the larger width tolerance band oriented to the right side indicating its tolerance.
The value of the resistance is given in the form:
R = AB × C ± D%
Where,
‘A’ and ‘B’ indicates the first two significant figures of resistance (Ohms).
‘C’ indicates the decimal multiplies.
‘D’ indicates the tolerance in percentage.
The table for the resistor color code is given below:
