What is the main composition of the brushes of a dc supply
1 answer
The main composition of the brushes of a DC supply is typically made of carbon or graphite. These materials are chosen because they have good electrical conductivity and are able to withstand the high temperatures and friction that occur during operation. The brushes are responsible for transferring electrical current from the power source to the rotating armature of the DC motor or generator. Over time, the brushes may wear down and need to be replaced to ensure proper operation of the DC supply.
