Question:

What is the difference between a generator and alternator?

Inactive
Nayyar M.
Answer:

The major difference between the alternator and the generator is that in alternator the armature is stationary and the field system rotates whereas in the generator armature rotates and field is stationary. The armature of the alternator is mounted on the stationary element called stator and field winding on a rotating element. While the connection of a generator is just the reverse of it.

Answer:

False. The derivative f '(x) is given by f '(x) = x / | x | f '(x) is undefined at x = 0 and therefore x = 0 is a critical point of function f given above. (see question 1 above).
