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.
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.
Value of resistor Yellow violet yellow gold color code?
470K ohm at 5% tolerance
Difference between measured value using multi-tester and color code value using resistor color coding?
(coded value - measured value) /coded value x 100

A 0.1 ohm resistor is color coded brown (1) black(0) silver (x 10-2).
Resistor color coded orangeorange and brown has a resistance value of?
Orange, orange, brown is 330 ohms.
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 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%
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 are resistor values defined by?
Resistor value is defined by the Resistance the resistor offers in Kilo ohms/ohms value given by color codes on the resistor.
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.
Why uses the measured values of the resistors in calculating total resistance why not uses the color coded value?
The color coded value have a tolerance (last color ring). The usual is 2-5%. While in most case this has little influence, in certain cases it can be important.
How do you read the value off a resistor?
