The commutator in the Stewart and Gee's experiment is used to change the direction of the current flowing through the coil in the magnetic field, thus maintaining a unidirectional torque on the coil. This helps in making the coil rotate continuously without getting stalled due to the change in direction of the current.

What is the purpose and functionality of the commutator function in a mathematical context?
The commutator function in mathematics is used to measure how two mathematical operations interact with each other. It helps determine if the order in which operations are performed affects the outcome. The commutator function is important in various mathematical fields, such as group theory and linear algebra, for studying the properties of mathematical structures.
What is the significance of the exponential commutator in the field of quantum mechanics?
The exponential commutator is significant in quantum mechanics because it helps describe the relationship between two operators that represent physical quantities. It plays a crucial role in understanding the behavior of quantum systems and is used in calculations to predict the outcomes of measurements in quantum mechanics.
Instruments and our senses Are used to make what during an experiment?
Instruments and our senses are used to collect and analyze data during an experiment. This data is essential for drawing conclusions and making observations about the experiment's variables and outcomes.
What is the measured result in an experiment?
The measured result in an experiment is the data or information collected during the experiment that is used to analyze and draw conclusions. It is typically recorded in numerical or qualitative form and reflects the outcome of the experiment.
Variable that does not change in an experiment?
A constant is a variable that does not change in an experiment. It is used as a point of reference or comparison to measure the effects of other variables.
What is use of commutator?
The commutator is used to convert the AC to DC
What is the use of Commutator?
The commutator is used to convert the AC to DC
Why commutator are not used in ac motors?
Because, the commutator segments are used for converting AC to DC.
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.
Is commutator used for both ac to dc and dc to ac conversion?
Yes
What material used to make a commutator?
A commutator is typically made from a combination of materials, primarily copper for its excellent electrical conductivity. The segments of the commutator are often insulated with a dielectric material, such as mica or plastic, to prevent short circuits between the conductive segments. In some cases, the commutator may also be coated with materials like silver to enhance conductivity and reduce wear.

What does the commutator in an electrical motor do?
If there is a commutator, it means you are dealing with a DC motor.The commutator acts like a switch to supply voltage to a revolving armature from the stationary brush assembly.A commutator has commutator bars, each seperated by mica insulation. Each coil of the rotating armature is connected to two bars that are in directly opposite positions across each diameter of the armature.The total number of commutator bars depends on the design of the windings on the armature: either "lap" or "wave" windings can be used on a DC motor or generator which is provided with a commutator.For more information see the answer to the Related question and also the Related link shown below.
What is the function of brushes and a split ring commutator and where are these items used?
Brushes and a split-ring commutator are key components in DC electric motors and generators. The brushes, typically made of carbon, maintain electrical contact with the rotating commutator, which reverses the direction of current flow in the windings as the rotor spins. This action ensures that the torque generated by the motor remains in the same direction, allowing for continuous rotation. In generators, the commutator converts the alternating current produced in the windings into direct current for output.
Purpose of slip rings?
slip ring is connect on shaft of motor to collect current from commutator without any complicate connection and with use of it resistors can be insert in circuit and therefore speed control of motor can easily achive
