What is the function of a commutator or slip ring?

Hint: We have to know that the direction of the current is dependent on the direction of charge low. The amount of the current depends on the two things. There are charges and potential differences in the coil. The potential difference is nothing but the voltage of the coil. The current is a scalar quantity.

Complete answer:
The function of the commutator or slip ring is used to change the direction of current for after every half rotation through the coil. The commutator or slip ring is nothing but the electrochemical system. The commutator or slip ring is used for transmitted power and signal from stationary structure to the rotating structure. The commutator or slip ring plays a vital role in space satellites, gun turrets, electro – optic sensors, gimbals or radar antenna for transmitted power and signal from stationary structure to the rotating structure. The commutator or slip ring is also used for simplifications of operation in the mechanism of the machine. The commutator or slip ring is also used for improving the efficiency of the mechanism of the machine. The commutator or slip ring is also used for transmit power and involves the rotation in the mechanism of a machine in any electrochemical device.
According to the above discussion we conclude the function of the commutator or slip ring is used to change the direction of current for after every half rotation through the coil.

Note:
We need to know that the cathode and anode are important for the cell of electrolyte. The cathode is a negatively charged electrode in the cell. The anode is a positive charged electrode in the cell. The cathode (negative charged electrode) in the cell attaches the positive ions in the electrolytic solution. The anode (positive charged electrode) in the cell attaches the negative ions in the electrolytic solution. The anion is a negative ion in the electrolytic solution of the cell. The cation is a positive ion in the electrolytic solution of the cell.
