5 اسئلة بعد اذا ممكن .. ضروري والله

1. Current flowing through the field coils:

a. Magnetizes the pole pieces
b. Makes the generator armature turn
c. Has no effect on the generator's magnetic field



2. The process of magnetizing the pole pieces involves:

a. Passing a magnetic field through them without change
b. Lining up the internal magnets of the pole oieces
c. Trying to get the tiny internal magnets of the pole pieces into random, helter-skelter positions so their fields cancel

b. The field current and armutre speed.
c. Resistance of the field coil abd armutre speed.



4. A field pole pices is said to be saturated when:

a. A small increase in field current produces a large jump in magnetic field strength.
b. Magnetic field strength increases when there is no increase in field current.
