Answer:
Carbon brushes tend to provide a path for the transmission of current between the dynamic and stationary part of the motor. Hence, the correct answer from the given options would be b) Provide a path for flow of current.
Explanation:
A carbon brush for an electrically powered motor is an electrical contact/touch which conducts current among the stationary part of motor and shifting part of the motor.
Carbon Brush programs consist of their use in electric powered cars and generators. These motor elements are seated in holders and are placed above the rotation commutator or slip ring.
