What is the function of carbon brushes in dc machine?
The carbon (graphite) brushes in a generator are used to connect external circuits in the generator to the rotor through the commutator. But you want to know what that means, right? Darn it, we always see these "trick" questions here. Okay, this is the scoop. The rotor in a generator is (usually) a group of windings. These are coils of wire. But they need to be connected to the "outside" or non-moving parts. Each coil has two ends, and these ends are connected to copper segments (sometimes called "lands") on the commutator. The segments are all in a ring around the end of the rotor, and the brush or brush sets ride on them. The other end of the brush(s) is(are) connected to wires to electrically connect them to appropriate places in the non-moving parts of the generator. The brush is conductive (naturally), and it is soft enough to provide a good "wear point" against the copper segments. The brushes do most of the "wearing away" in this application, and it is a fairly easy and straight forward evolution to replace them. In the motors of power tools, some of the units have a way to access the brush holder without taking the housing apart. Particularly the older ones. Anyway, it is said that a picture is worth a thousand words. Use the link below and take a look at the pictures. It's all there.
A carbon atom from carbon dioxide is used to change the five carbon sugar RuBP into?
The carbon atom from carbon dioxide is used to change the five carbon sugar RuBP into two three-carbon molecules. This process is known as carbon fixation and occurs during the Calvin cycle of photosynthesis. The three-carbon molecules produced are further processed to create glucose and other organic compounds.
What is a carbon rod?
A carbon rod is a solid form of carbon that is often used in devices like batteries, electrolytic cells, and arc lamps. It is known for its high melting point, good electrical conductivity, and resistance to chemical corrosion.
Which allotrope of carbon is used in superconductor?
The allotrope of carbon used in superconductors is called "fullerene," which is a molecule made up of carbon atoms arranged in a cage-like structure. Specifically, fullerene molecules like C60 or C70 are doped with other elements to achieve superconductivity at higher temperatures.
Which gas is used when fossil fuels burn carbon dioxide or oxygen?
When fossil fuels burn, oxygen is used as the gas that reacts with the carbon in the fuel to produce carbon dioxide. This process is known as combustion and is the reason why carbon dioxide is released as a byproduct of burning fossil fuels.

What are universal motor brushes made of?
the brush is a peice of carbon that is attached to the startor by a brush holder.
Why brushless screwdriver is more preferred over brush screwdriver. From where we can buy best electric screwdriver.?
