Carbon brushes are used to connect the rotating commutator of a DC machine with the external circuit. Carbon is selected because
- it has a negative temperature coefficient of resistance, i.e. its resistance falls with a rise in temperature.
- it is self-lubricating.
- it quickly shapes itself to the curve of the commutator.

Why use star delta gether for motor?
In a large power motor the starting current is too high if connected 'direct on line'. If you start a motor on 'star' connection it uses less current to get it going before the 'delta' connection takes over.
What form of carbon which the plants use in making food?
Starch.
Will carbon build up keep a motor from firing in a Chevy traverse?
Yes, Chevy Traverses can suffer from misfiring if there is carbon build up on the motor. Many people use seafoam to correct this problem.

Why is graphite suitable for making carbon contacts?
Graphite is suitable for making carbon contacts because it is a good conductor of electricity, has low resistance, and is chemically stable. Its layered structure allows for easy transfer of electrons, making it ideal for use in electrical contacts.
Can you use high carbon steel for making a silver casting mold?
