The essential difference between an AC generator and a DC generator is that

  1. AC generator has an electromagnet while a DC generator has permanent magnet.
  2. DC generator will generate a higher voltage.
  3. AC generator will generate a higher voltage.
  4. AC generator has slip rings while the DC generator has a commutator.

 

Answer

AC generator has slip rings while the DC generator has a commutator

 

Explanation - An AC generator has two rings called slip rings. These full rings help in changing the direction of current, thus producing AC current

 

A DC generator has two half rings called commutator. These half rings help keep the direction of current same, thus producing DC current.
