They absorb moisture which can change resistance properties of the resistor with time. The carbon composition resistor is a type of fixed resistor that reduces or restricts the electric current flow to a certain level. However, no responsibili ty, financial or otherwise, is accepted fo r any consequences arising out of the use of this information. Carbon composition resistor definition, construction. General note tt electronics reserves the right to make changes in.
That is why carbon composition resistors are sensitive to ambient relative humidity. The carbon resistor contains carbon coated onto a ceramic core. The resistive material for the carbon composition resistor is a blend of graphite, ceramic dust and resin. Carbon composition resistors, often called carbon composite, or even carbon comp resistors are an old type of resistor that is not used in new equipment these.
