Construction carbon composition resistor.

What are resistors made up of. This type of resistor is widely used today. A thin pure carbon film is deposited on an insulating cylindrical core. These are made of a non conductive rod with a thin carbon film layer around it.

This layer is treated with a spiral cut to increase and control the resistance value. A carbon pile resistor is made of a stack of carbon disks compressed between two metal contact plates. Generally wire wound resistors are more precise and more stable at higher operating temperatures.

Carbon composition ccr the resistive element is made from a mixture of fine carbon particles. Resistors can be constructed out of a variety of materials. There is a variety of ways resistors are made.

Its one type of resistors among several. Carbon composition resistors have a body of a mixture of fine carbon particles and a non conductive ceramic. Resistor materials wirewound ww these types are made by winding resistance wire in a spiral around.

There are also carbon film resistors and metal film resistors. These resistors are used when an adjustable load is required for example in testing automotive batteries or radio transmitters. Most common modern resistors are made out of either a carbon metal or metal oxide film.

Generally wire wound resistors are more precise and more stable at higher operating temperatures. Carbon composition resistors are resistors that are made with carbon or graphite mixed with a binding material. Carbon composition resistors were used for over 100 years.

Carbon film resistors have the carbon film on the ceramic former. Most smaller low power 2w are carbon or metal film for their active element. Resistors like this are much cheaper to make and are called carbon film.

In these resistors a thin film of conductive though still resistive material is wrapped in a helix around and covered by an insulating material. Metal oxide film resistor. Out of all the resistors carbon film resistors have the greatest tolerances and changes to temperature fluctations.

Adjusting the clamping pressure changes the resistance between the plates. The most common ones are carbon and wire wound.
