Standard Resistor Code
Standard resistors use colored bands to represent the value of the
resistor. To read 4-colored bands, the first two digits represent the
base value, the third is a multiplier and the last band is the
tolerance. For a 5-colored band, the first 3 digits represent the base
value, the 4
th digit is the multiplier and the last digit is the tolerance.
