Question

1
An important difference between alterna-
tive generators and direct generator is?
options
A) the alternative generator has an electromagnet but the direst generator has a permanent magnet.
B)Director generator has potential difference.
C) Alternative generator has high potential difference.
D)Alternative generator has split rings and the direct Generator has cummutator.​

Answer 1

Answer:

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

AC generator has slip rings. A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. A slip ring can be used in any electromechanical system that requires rotation while transmitting power or signals.

DC generator has a commutator. The commutation in DC machine or more specifically commutation in DC generator is the process in which generated alternating current in the armature winding of a dc machine is converted into direct current after going through the commutator and the stationary brushes.

Answer 2

Answer:

alternative generators have split rings and direct generators have commutators.
