Electronic Resistors Color Codes
Resistors are normally identified with a code. This code is visible as external bands circling the resistor.
Note: when substituting resistors, and the identical resistor is not available, you almost always be able to use a resistor with a value that falls within the original resistor 10 or 20%.
