Hi,
I have a resistor that is showing up as 56.0 Ohms on a multimeter but the
colour code seems to say 560 Ohms.
Green Blue Black Gold Brown
5 6 0 ?? 1% Tolerance
What does the gold mean?
Thanks for ya time guys.
codes are correct.
third band is your multiplier., this would make the
R 56 Ohms. 0 meaning no zero's after 56. 1 meaning 1 zero
which would be a brown ring how ever,
the gold band is your +/- 5% accuracy of the marked
reading.
the brown band, because it comes after the tolerance
reading normally used for quality and other markings.
you make see at times were you only have 2 color bands
and then a gold or Silver band, this is a fraction multiplier.
gold being X 0.1 of the first 2 digits, and silver being
x 0.01 etc./
you make also see another gold/silver band following it that
would then indicate the tolerance.
there are in some cases for more precise values 4 bands for
R value and then the Multiplier. you will know when you have one
of these due to the fact that gold/silver band will not appear until
after 4 color bands. R,R,R,M,T instead of the R,R,M,T
etc..
hope that helped some.
