Why the color coded value of a resistor is differ from the value read from the tester?
The color bands show the nominal resistance. The actual resistance is within some percentage (tolerance) of the nominal resistance, so the measured resistance is close to the nominal but not exactly the same. Also resistance varies with factors like temperature and age of the device.

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 color code of resistor value 0.1?
A 0.1 ohm resistor is color coded brown (1) black(0) silver (x 10-2).
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.
What is the color code for a 330 ohm resistor?
orange-orange-orange
What is the color of a resistor 1.5kohm?
It is brown, green, red, and gold. See the related link.
Difference between measured value using multi-tester and color code value using resistor color coding?

What is color coded?
In electronics, a color code is used to show the value of a resistor. Color codes can be used to communicate just about anything that one might want to.
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 you know Which wires are which when installin a stereo?
If you are using a wiring harness they are color coded. Otherwise, get a voltage tester to find the "hot" wire and the memory wire. you will have to trace the speaker wire.
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.
Why are the bands color- coded?
the bands are color- coded because it tells you what is what and what energy it have.
Why are the band color-coded?
the bands are color-coded because it tells you what and what energy it have .
How do you work out resisters percentage?
On a color coded resistor, there are normally four color bands. The first three represent the value of the resistor and the fourth represents the tolerance of the resistor, i.e. the acceptable variation as a percentage from the stated value. No fourth band allows +/- 20% Silver allows +/- 10% Gold allows +/- 5% Red allows +/- 2% Brown allows +/- 1%
What is the resistor color code and how is it used to identify and select resistors?
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.
