Hi Everybody
Please someone can help me to find out resistor value from color code that is attached a picture copy.

Thanks

 

4.71Kohms 2%

 

If the two middle bands are gold, it looks like 4.7 ohms, 5% tolerance:

Yellow - 4
Violet - 7
Gold - 0.1 - Multiplier
Gold - 5% - Tolerance
Red - 50 ppm - Temperature coefficient

Looks to me like Y-V-G-G-R.

If the final red band is the tolerance band, that means that it is a 2% resistor. However, that means that the last gold band is the multiplier and the other three bands are digit values. But since gold is not a valid digit color, this can't be the interpretation.

The next most likely is that the final red band is indicating something else. Most likely, this would be the temperature coefficient, which means that it is a has a 50 ppm tempco. This then means that the last gold band is the tolerance (5%) and the first gold band is the multiplier (0.1 Ω), That would make the value 4.7 Ω.

The concern here is that tempco ratings are normally only seen on six-band resistors. But there are a lot of "nonstandard" resistor codings out there, so who knows?

My best guess is that it is a 4.7 Ω resistor and that the red band means tempco or perhaps something else.

 

I don't see any gold bands.
What I see is:
Yellow = 4, first digit
Violet = 7, second digit
Brown =1, third digit
Brown =1, number of zeros
Red = 2, % tolerance

4,710 ohms, 2%

What does it actually measure?

 

4.7 ohms 5% 50 ppm/K
