How To Calculate Resistor Value Using Color Code

In case of 3 band and 4 band resistors the first two color bands are showing the significant figures and their values while in 5 band and 6 band resistors the 1 st 2 nd and 3 rd color bands are showing the significant figures and related values.

Resistor values and color codes. The resistor color code calculator decodes and identifies a value and tolerance of 4 band wire wound resistors. Brown 1 red 2 gold 5 silver 10 if resistor has no fourth tolerance band then the default tolerance would be at 20. Resistors can have 3 4 5 or 6 color bands printed on them.

The printed colors gives an accurate representation on the value of the resistor. More online conversion calculators at digi key. Practically all leaded resistors with a power rating up to one watt are marked with color bands.

Color bands are used because they can be easily and cheaply printed on a small electronic component. The colour code used to denote the tolerance rating of a resistor is given as. Resistors have standard colors for identification of the resistance.

In resistor color codes each color shows a specific value. For very small electronic components a color code is used instead of printed text. Color coding is a method used to indicate the resistive value tolerance and temperature coefficient of resistors with low wattage rating because of their small size.

Color coding is also used for capacitors inductors and diodes. This color code indicates the value rating and tolerance.
