## Introduction

A resistor is possibly the maximum resistor color code not unusualplace constructing block utilized in circuits. Resistors are available in many styles and sizes this device is used to decode facts for color-banded axial lead resistors.

## five Band Description

The quantity of bands is essential due to the fact the deciphering adjustments are primarily based totally upon the number of color bands. There are 3, not unusualplace types: four-band, five-band, and six-band resistors. For the five-band resistor:

Band 1 – First huge digit.

Band 2 – Second huge digit

Band three – Third huge digit

Band four – Multiplier

Band five – Tolerance

Resistance Value

Black – 0

Brown – 1

red – 2

orange – tree

yellow – four

green – five

Blue – 6

violet – 7

grey – 8

white – 9

black – x1

brown – x10

red – x100

orange – x1K

yellow – x10K

green – x100K

blue – x1M

violet – x10M

grey – x100M

white – x1G

gold – .1

silver – .01

## An instance of a resistance fee is:

band 1 = orange = three,

band 2 = yellow = four,

band three = green = five,

band four = blue = 1M

fee = 345*1M = 345 Mohm

## Resistance Tolerance

The 5th band is the tolerance and represents the worst-case version one would possibly count on from the nominal fee. The color code for tolerance is as follows:

brown – 1%

red – 2%

orange – three%

yellow – four%

green – .five%

blue – .25%

violet – .1%

gray – .05%

gold – five%

silver – 10%

## An instance calculating the variety of a resistor fee is:

If the nominal fee became 345 Ohm and the fifth band of the resistor became gold (five%) the fee variety could be nominal +/- five% = 327. seventy-five to 362.25A resistor is diagnosed via way of means of its sample of the color of bands. There are four, five, and six-band resistors. To calculate the resistance of a resistor, you may choose the best color bands withinside the above resistor color code calculator.

## How to calculate the resistance?

Just have a glance at the resistor color code chart beneath and notice the calculations, and how the resistance fee is calculated in keeping with this chart.

## five-band resistor calculation formulae

Where,

`a` represents the first huge digit, that’s the primary band color of the resistor.

`b` represents the 2d huge digit, that’s the second band color of the resistor.

`c` represents the third huge digit, that’s the 0.33 band color of the resistor.

`d` represents the 4th huge digit, that’s the fourth band color of the resistor and that is the multiplier fee utilized in the system.

`e` represents the fifth huge digit, that’s the 5th band color of the resistor and that is the tolerance fee of the resistor.

## Tolerance

Let`s take an instance of a five-band Printed circuit board in china resistor with the colors given withinside the above image (brown, green, red, black, and gold).

So in keeping with the system the resistance will be 152 * 1 = 152 Ohms with five% tolerance.
