Classification of resistors consists of three main properties.
Resistance, measured in ohms,
Tolerance of the resistance value, shown as a percentage,
Power handling capacity, measured in watts.
    The first two can be taken from the table above using the 4 or 5 band code as appropriate. The power handling capacity is not normally indicated with bands but can sometimes be printed on the component itself, particularly for the higher wattage resistors
