how to read resistor color code?Ok read the article..

Example 4-color code
Before you can turn the color code in the resistance value, one must first make sure that you read the color rings in the correct order.
5600 Ohms = 5.6 kOhmDer first color ring is the one who was served very briefly in the edge of the casing. If the resistance is large enough body, is the fourth ring, indicating the tolerance level should be slightly apart.
The resistance arises from a two digit number (IEC) number that multiplied by the decade, our example:
1. Ring: Green = 5
2. Ring: Blue = 6
3. Ring: red = returns 10 ² = 100: 56th 100 = 5 600 W (pronounced Ohm)
4. Ring: gold = ± 5% tolerance

5% from 5 600 are 280, i.e. The nominal value of 5 600 W may in fact be up to 280 W small (5 320 W) or greater than 280 W (5 820 W).


The resulting value is 5 600 W. We have to keep:
Figures> 1 000 W to 1 kW in (read: convert 1 kg W)
Figures> 1 000 000 W to 1 MW in (ie: 1 Mega Watts) format.
What is the final result of 5.6 kW.


Example 5-color code
5 600 Ohms = 5.6 Ohms = 5k6 has a resistance five colored rings, thus forming a three-digit number, multiplied with the appropriate power of ten, the resistance value.
1. Ring: Green = 5
2. Ring: Blue = 6
3. Ring: black = 0
4. Ring: brown = 101 = 10 gives: 560th 10 = 5 600 W
5. Ring: red = ± 2% Tolerance
Bottom line: 5.6 kW / ± 2% Tolerance


Transformation of a number in the color code
The following resistance value should be coded: 4.7 MW / 5%
1. Step: Convert to W = 4 700 000
2. Step Set: Two-digit number and magnitude
47 ... which we must multiply the 47, so 4 700 000
arise?
47. 100 000 = 47th 105 = 4 700 000
3. Step: 1 Ring = 4 = yellow
2. Ring = 7 = purple
3. Ring = 5 = green
4. Ring = 5% = gold


The value is 3 W at 2% tolerance.
1. Step: Convert to a two-digit number = 30
2. Step ... with which we must multiply the factor 30, thus 3 ensteht? 30th 0.1 = 30th 10-1 = 3
3. Step: 1 Ring = 3 = orange
2. Ring = 0 = black
3. Ring = -1 = gold
4. Ring = 2% = red

IEC series
An IEC (International Electrotechnical Commission) number indicates the variation of the nominal value within a decade.
In E6, the earliest series, there are six 0-10 denominations and a tolerance of 20%. In the E12 it's the spirit 12 denominations and 10% in the E24 .....
It has been with the help of Ohm's law, a resistance value of eg Buy a calculated 64 W, it will be this resistance but can not. According to E24, there are only 62 W in trade or 68 W.
The numbers in the series were chosen so that it is due to the tolerance to minor overlaps. Do you need an exact value, one must resort to trimming potentiometers or spindle trimmers.
