Resitor Color Code
This is a one example of a resistor.... It is a 5-Band-code
Do you know how to read it to find out what's the minimum and maximum resistance??
This is how I do it...
First I will found the tolerance band...that is the last band after the
big gap...in the picture above the color of the tolerance band is a gold.. that is plus and minus 5%
Then I look up the color code table
Then I always read it backwards....I start with the multiplier and put all the zero then the rest of the bands...
In the resistor above the multiplier is black...the multiplier is always tells you how many zero's you have in the band..... black has no zero's and don't
have to put it... then
White = 9
Orange= 3
Orange= 3
933 is the reading up to the fourth band then plus and minus it to 5% to get the minimum and maximum resistance...
5% of 933 is...46.65
Minimum: 933-46.65 = 886.35 ohms
Maximum: 933+46.65= 979.65 ohms
I hope this thing helps you...
Thnx,
Dan
