Did u c armature in an electrical generator

Answer 3

U hv c armature for clear concept

Answer 4

The first one is B. Electric generator. It is another term for AC generator which transforms M.E to E.E, like what is used in a windmill.

The second one is B. The armature spins in the same direction continously because the current reverses in direction at every half turn in one complete spin.

Hope you got it!
