Why carbon is used in brushes instead of semiconductor material in motor?
There are a number of reasons, including: 1. Carbon is self-lubricating. 2. Carbon has a negative temperature coefficient of resistance, which means that its resistance falls as its temperature increases -which is opposite that of metals such as copper. 3. Carbon is softer than copper, so will not damage the commutator. 4. Carbon will acquire the shape of the commutator segments and, so, will ensure maximum contact with them.
What are the materials used to make brushes in Electrical Generator?
Carbon, due to it's high melting point.
What is the use of brushes in an electric motor?
Brushes transfer electricity to the commutator which is connected to the winding on the armature. The brushes and commutator form a electrical connection that is good when the brushes are stationary and the commutator is spinning. The commutator on a DC motor is sectioned to power different windings at different times, creating moving field necessairy to pull the armature off a direct current.
Is copper used in plumbing?
Yes, copper pipes are used extensively in plumbing.
Can Aluminum mylar-tape-shielded cables be used instead of Copper braid-shielded cables for instrumentation cables?
Actually, aluminum mylar tape shielded cables are better than copper braid shielded cables for instrumentation cables.
Why carbon brushes are used in DC machines?
Carbon brushes used in DC machines because carbon is soft material and it does not generate spikes when contact with commutator
Why carbon brushes are most used in dc?
Carbon is used because it is soft and does not damage the commutator. This means that the brushes must be replaced at intervals, and the powdered carbon scraped out from between the segments of the commutator.

How do you clean copper used in plumbing?
Sandpaper, emery cloth or wire brushes sized for the different sizes.
Why carbon brushes are used in motor.type of brushes.and why specifically carbon brushes are usedwhy other type are not used most?
Low resistivity to current , high hardness and material strength gives long brush life under severe operating conditions
Why are copper wires used instead of steel wires?
I think copper is cheaper.
What are the materials used to make brushes in Electrical Generator?
Carbon, due to it's high melting point.
What is a carbon brush used for?
Some kinds of single phase ac electric motor use commutators. They are the kind where the field winding is connected in series with the armature and they are typically used in non-battery-powered electric drills, hair dryers and home vacuum cleaners.
Does copper have carbon?
No, both copper and carbon are elements. Carbon is the basic element involved in organic chemistry. Copper is a very important element which is used in the pure form in a variety of situations, especially electrical conduction. It is also a good thermal conductor so is commonly used as a "heat sink" to radiate heat away from sensitive electronics. Copper may be combined with carbon in certain compounds, often called "organometallic" compounds but as the question is posed, copper does not contain (have) carbon in it. Good luck, Nitrous
What is copper thermite?
Copper thermite is a type of thermite where instead of the iron oxide, copper oxide is used instead. The reaction produces pure copper metal, but this thermite gets a little more splattery than the iron thermite.
What is the only non metal that is a good electrical conductor?
Carbon in the form of graphite is used as an electrical conductor (the brushes in electric motors)
Which two metals are used in a bimetallic strip?
A bimetallic strip usually consists of steel and copper. In some cases brass is used instead of copper.
