How to Use the Resistor Color Code Calculator

Are you having bother reading resistance color codes? If your answer is affirmative, then this tool is specifically designed for you! Our resistance code Calculator may be a handy tool for reading carbon-composition resistors whether or not it is a 4-band.
To use this tool, merely click on a selected color and range and watch however the particular bands on the resistance illustration amendment. The resistance price is displayed on the sector below along with the tolerance and also the temperature constant.
An electrical device is known by its pattern of color of bands. There area unit four, five and half dozen band resistors. To calculate the resistance of an electrical device, you’ll be able to choose the suitable color bands within the on top of electrical device code calculator.

How to calculate the resistance

As shown on top of, a carbon-composition electrical device will have four to six bands. Resistor 5-band electrical device is additional precise compared to a 4-band kind attributable to the inclusion of a 3rd significant figure. A 6-band electrical device is sort of a 5-band electrical device, however, includes a temperature constant band (the sixth band).

How to calculate the resistance

Mnemonics were created to simply study the sequence of the colors. the foremost standard memo technical is “Big Boys Race Our Young Girls But Violet Generally Wins” wherever the primary letter of every word corresponds to the primary letter of the color.

If the color is found on the third band for a 4-band kind or the fourth band for a 5-band and 6-band kind, then it is a number.

The fourth band (or fifth for the 5-band and 6-band) indicates the tolerance values. Here, 2 colors are extra(gold and silver).

Calculating resistance for a 5-band resistor

Resistance = ABC x D ± E%

Where,

‘A’ represents the 1st digit, that is that the 1st Band color of resistance.

‘B’ represents the 2nd digit, that is that the 2nd Band color of resistance.

‘C’ represents the 3rd significant figure, that is that the 3rd band color of resistance and this can be the number price. 

‘D’ represents the 4th figure, that is that the 4th Band color of the electrical device and this can be the tolerance worth.

‘E’ represents the 5th significant figure, that is that the 5th Band color of an electrical device and this can be the tolerance price of an electrical device.

Name 4 Band Resistor

Description
A 1st Band Color  1st  significant digit
B 2nd  Band Color  2ndsignificant digit
C 3rdBand Color  3rdsignificant digit
D 4thBand Color Multiplier
E 5th   Band Color Tolerance

Let’s take the example of a 4-Band resistor with the colors given in the above image (brown, blue, red and gold).

So according to the formula the resistance will be: 103 * 100  = 10300 Ohms or 10K3 Ohms with 5% tolerance.

Color Code Exceptions

5th Band Resistor with the 4th Band of Gold or Silver

Five band resistors with the fourth band of silver or gold type Associate in Nursing exception, and are used on specific or older resistors. the primary 2 bands represent the numerous digits, the third band could be a multiplication issue, the fourth band is for tolerance and therefore the fifth band is for the temperature constant (ppm/K).

Single Black Band or Zero-Ohm Resistor

A single black band on an electrical device is termed a zero-ohm electrical device. Basically, it’s a wire link wont to connect traces on a computer circuit board (PCB) that are packaged within the same physical package format as an electrical device. This packaging permits the zero-ohm electrical device to be placed on the care mistreatment identical instrumentation usually wont to place alternative resistors.
