Resistor Initial Digits
The resistor coloured bands for determining the initial digit values needed to calculate a resistor resistance value are Bands 1 and 2 for four band resistors, Bands 1, 2 and 3 for five and six band resistors and can to be determined by looking at the Table of Resistor Color Codes above.
These initial digits are not added together but placed side by side to result in a full number, for example if Band 1 colour is Green, value of green is “5”, if the 2nd Band colour is brown, the value of brown is “2”, therefore the full number is “52”.
Using the above example, the resistance calculation would be 52 x Multiplier = Resistor Resistance.
