Carbon composition resistors are made from a moulded carbon powder that has been mixed with a phenolic resin to bind and create a uniform resistive body. It is then surrounded in an insulating case after attaching end leads.

The power rating of a resistor describes the amount of power that the resistor can dissipate safely.

Each of the colour bands has a specific meaning. The first two colours give the base value of the resistor, the next gives the multiplier and the final band the tolerance. If a resistor has five bands, it is a more precise resistor, in which the first three bands represent the base values, and the fourth and fifth represent the multiplier and tolerance respectively.
