3. How does a split ring commutator work? * Coil rotation Coil Commutator a) Swaps the contact every full turn, so that the left-hand and right-hand arms of t coil always experience a force in the same direction. b) Swaps the contact every half turn, so that the left-hand and right-hand arms of coil do not experience a force in the same direction. c) Swaps the contact every half turn, so that the left-hand and right-hand arms of coil always experience a force in the same direction.

Expert Solution
Step 1

Now we have been seen that in the armature, we are getting a AC voltage in DC generator the o/p voltage across brushes must be DC. Hence we have to convert AC into DC. For this purpose, we split ring or commutator.

 

a) Action of commutator
