Question

Explain.
Dc generator has a commutator that uses dash ring.​

Answer 1

Explanation:

ANSWER

A split-ring commutator makes the current change direction every alternate half-rotation, whereas a slip-ring commutator merely maintains a connection between the moving rotor and the stationary stator. As the direction of current itself changes every half-rotation and split ring commutator reverses the direction of current every alternate half rotation, it essentially converts current direction in every half-cycle to positive. Hence, it converts AC to DC.
