What is the resistor color code and how is it used to identify and select resistors?
GeographyMan
The resistor color code use to help to identify the resistance of the resistor. There are four color in the resistor that help to identify the resistance of the resistor. The first and second color represent the numerical value of the resistor. The third color represent the multiplier. The four color represent the tolerance.

Why do resistors have a color code?
Colour code used to identify resistance of the resistor
How to identify a 470 ohm resistor?
Resistors are color coded to denote the value of the resistor as well as the multiplier. In your case a 470 ohm would be colored as Yellow Violet Brown corresponding to 4, 7 and a multiplier of 10^1.
How calculated the value of resistor that is to be used in particular circuit?
To read the value of a resistor: Resistors are color coded, you can use the chart found below And how accurate the values of resistors are is their tolerance, also found in the chart
How do manufacturers of resistors indicate the value of the resistance?
They use a color code. Colored bands on the resistor that tell the value. Some precision resistors have their value written on them.
How can a technician identify a wire wound resistor that is color coded?
The same way he/she can identify a composite resistor that is color coded or a metal film resistor that is color coded: by reading the color code bands. They all use the same color code. If for some reason the color bands are damaged and unreadable, the resistor will have to be removed and measured with a meter. However this reading may be incorrect as whatever caused the color bands to become unreadable may have also damaged the resistor, changing its value. Verify the value on the schematic!
What is the Technique used in resistors is coding or decoding?
If you want resistor color code, look in wikipedia electronics color code
What happens to the value of a resistor when it goes bad?
we can say that a resistor gone bad if 1. its resistance is different than that printed by the color code 2. doesn't conduct any current Resistors normally will burn open. Carbon resistors almost always do this, while wireound resistors can lower in resistance. They may still allow current flow, but it will not be correct.
What does the third and of a resistor mean?
That depends on the resistor, the resistors that are color coded come with either 4, 5 or 6 bands. On resistors with 4 bands, the 3'rd band is the multiplier. F.ex if we have a Resistor colored brown:red:orange it would mean 1 : 2 : 3 which translates to (10+2)*10^3, or 12*1000 = 12k Ohm On resistors with 5 or 6 bands, the 3'rd band is just another digit For examle a 5-band resistor starting with brown|red|orange|yellow would mean 1 | 2 | 3 | 4 which translates to (100+20+3) * 10^4 or 123*10000 = 1,23M Ohm
Why are fixed resistors values indicated by colors?
Because the actual resistor is too small to print numbers, so color bands and math are used instead. I just don't know how to calculate the values.
History of the resistor color code?
According to what i have read is that... there once was an electrical engineer... and he had difficulty in remembering the resistance values of the resistors and used to mix them up! That engineer was also known as a good artist, so he used the colors and marked them so that it would be easy for him to remember. This idea was then followed by many others and hence color coding on resistors spread and is now used internationally.
What is a system used to label resistors?

What is the color coding for resistors?
orange-orange-orange
