|Resistor Color Code Calculator
Select colors from select box, click on calculate button
and result will be displayed.
Color bands are used to signify the resistance value with each
color signifying a number and these color
bands are closer to one end of the resistor than the other.
Black 0 Brown 1 Red 2 Orange 3 Yellow 4
Green 5 Blue 6 Violet 7 Gray 8 White 9
This holds true for the first 2 color bands.
The third color band is
the multiplier of the first 2 bands where Black=1; Brown=10; Red=100;
Orange=1,000 and so on.
The third band (the multiplier)
is based on the number 10 raised to the power of the color code. For
example, red in the third band is 10² or 100.
This third band (the multiplier) also has 2 new colors where gold = .1 and
silver = .01.
The 4th band is the tolerance of the resistor. It shows how
precisely the resistor was manufactured. Gold = 5% , silver = 10% and
no band whatsoever = 20%.
