The brushes are made up of carbon because it has low friction as compare to other materials and cheaply also, but carbon has high resistance due to which output can vary. So we mix carbon with copper metal to reduce resistance.
Note that we cannot use copper only for brushes because it creates more friction with commutator.

What are universal motor brushes made of?
the brush is a peice of carbon that is attached to the startor by a brush holder.
How are machines made?

How is graphite used by people?
we use graphite by ever time we use a pencil thats one way we use graphite. Graphite is also used in the making of sports equipment and other every day items since graphite is a lighter material to work with. Like a badminton racquet can be made from graphite to make it lighter.
What were Victorian brushes made of?
Victorian brushes were typically made with a variety of materials, reflecting both functionality and aesthetic appeal. The handles were often crafted from wood, bone, or ivory, while the bristles could be made from natural sources such as horsehair, boar bristle, or even feathers. Some decorative brushes featured ornate designs and embellishments, showcasing the craftsmanship of the era. These brushes were used for grooming, cleaning, and in some cases, as fashion accessories.
What is the function of brushes and a split ring commutator and where are these items used?
Brushes and a split-ring commutator are key components in DC electric motors and generators. The brushes, typically made of carbon, maintain electrical contact with the rotating commutator, which reverses the direction of current flow in the windings as the rotor spins. This action ensures that the torque generated by the motor remains in the same direction, allowing for continuous rotation. In generators, the commutator converts the alternating current produced in the windings into direct current for output.
What material is graphite made of?
Graphite is an allotrope of Carbon. It is made of Carbon.
Is graphite made out of graphite?

What is the difference between carbon graphite and graphite?
Carbon graphite refers to a composite material made of carbon and graphite, often used in high-performance applications like aerospace. Graphite, on the other hand, is an allotropic form of carbon with a layered structure, known for its lubricating properties and use in pencils and electrical applications.
