Electronic Resistor Color Codes
Resistor values are marked with small colored stripes. The first two stripes represent numeric values and the third stripe is a multiplier. The fourth stripe gives you the resistor’s tolerance — that is, it tells you how close to the indicated value you can expect the resistance to actually be.
For example, a resistor with brown, black, orange, and gold stripes is a 10,000 whose actual resistance may vary by as much as 10%.
