Question

What change should be made in an a.c. generator so that it may become a d.c. generator?

Answer 1

Hey mate....

Here's your answer....

The slip rings used in the AC generator can be removed and split rings can be replaced instead. Now, AC generator uses concave magnets, change them and lastly remove the coil and replace it with armature instead. The AC generator will start functioning as a DC generator.

Hope this will be helpful to you mate......
