Different codes are used for wire leads on devices such as transformers or in building wiring. This is to prevent having metal particles in the coating. This convenient index was created by radio manufactures association now part of electronic industries alliance in early 1920s. A separate code, the 25pair color code, is used to identify wires in some telecommunications cables. Resistor colour code solver is a featured resistor value calculator which offers both color code to value and value to color code conversions.
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 color code consists of various color bands, which indicate the resistance values of resistors in ohms as well as the tolerance rating. Thus resistors play an important role in running circuits. This may be difficult on small or oddly colored resistors. If you would like to print this out and hang it near your workbench, you can download the pdf. To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change. Resistors and the color codes although the color code is not only for resistors, the ability to read the resistor color code is more required among engineers and scientists. This is all about different resistors and the colorcode identification for resistance values.
Resistors can be integrated into both hybrid and printed circuits. Calculating resistor values the fifth bands is used to determine the percentage. In the case of a 3 or 4 band resistor, the first two band indicate the significant digits and the third indicates the multiplier. The color bands are always read from left to right starting with the side that has a band closer to the edge. Resistor color codes and values for practical application brief. There are many things to keep in mind with resistors like electrical color codes, conversions, values, and sizes. The 4 color bands on the left side are grouped together to represent the resistance value of a resistor and the 5 th color band on the right side indicates the tolerance of the resistor the 1 st color band indicates the 1 st significant value or 1 st digit of the resistors value the 2 nd color band indicates the 2 nd significant value or 2 nd digit of the resistor value. Here is the tutorial about 3, 4, 5 and 6 band resistors color codes, tolerance letter coding. Our resistor color code calculator is a handy tool for reading carboncomposition resistors whether its a 4band, 5band or 6band type. Because carbon resistors are physically small, they are colorcoded to identify their resistance value in ohms.
