This calculator converts the colour bands which are found on resistors into their values.
Resistance = n/a
Tolerance = n/a
Temperature Coefficient = n/a
Prefered Resistor Values
Resistors are available in a number of standard (Prefered) ranges or series and these are: E3, E6, E12, E24, E48 and E96. The E denotes the number of values the series contains per decade.
