Eltronicschool. - The most popular component in electronic devices is resistor. There are many kinds of resistor provided in this time, one of them is 4 band resistor calculator.
In this season we will show you information about the introducing for 4 band resistor calculators.
Introduction
A resistor is a perhaps the most common building block used in circuits. Resistors come in many shapes and sizes this tool is used to decode information for color banded axial lead resistors.
4 Band Description
The number of bands is important because the decoding changes based upon the number of color bands. There are three common types: 4 band, 5 band, and 6 band resistors. For the 4 band resistor:
Band 1 – First significant digit.
Band 2 – Second significant digit
Band 3 – Multiplier
Band 4 – Tolerance
Resistance Value
The first 4 bands make up the resistance nominal value. The first 2 bands make up the significant digits where:
black – 0
brown – 1
red – 2
orange – 3
yellow – 4
green – 5
blue – 6
violet – 7
grey – 8
white – 9
The 3rd band or multiplier band is color coded as follows:
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 example of a resistance value is:
band 1 = orange = 3,
band 2 = yellow = 4,
band 3 = blue = 1M
value = 34*1M = 34 Mohm
Resistance Tolerance
The fourth band is the tolerance and represents the worst case variation one might expect from the nominal value. The color code for tolerance is as follows:
brown - 1%
red - 2%
orange - 3%
yellow - 4%
green - .5%
blue - .25%
violet - .1%
gray - .05%
gold - 5%
silver - 10%
An example calculating the range of a resistor value is:
If the nominal value was 34 Ohm and the 4th band of the resistor was gold (5%) the value range would be nominal +/- 5% = 32.3 to 35.7

Hmm, it seems like your site ate my first comment (it was extremely long) so I guess I’ll just sum it up what I had written and say, I’m thoroughly enjoying your blog. I as well as an aspiring blog writer, but I’m still new to the whole thing. Do you have any recommendations for newbie blog writers? I’d appreciate it.
