✨✨✨DIFFERENCE BETWEEN AC AND DC GENERATOR ✨✨✨

✅In Ac generator it’s constant it’s always the rotor.
In Dc generator, the armature may be the stator or the rotor.

✅Ac generator works with brushes and slip rings and it doesn’t contain commutator.
Dc generator works with one commutator additional to the brushes and slip rings.

✅Ac generator produced a very high voltage which varies in amplitude and time, and it has a normal 60 or sometimes 50 HZ.
DC generator produces a relatively low voltage which is constant in amplitude and time, the output frequency equals zero.


✅Ac generators used for power generation in office and home to power small and electrical appliances like:

✔Vacuum cleaners.
Food Mixers.
Dishwashers.
Refrigerators.
Juicers.
And electrical fixtures.
That’s because AC generation and transportation across long distances is very easy.

Dc generator is used to power very large electric motors such used for:

✔Subway systems.
Also, it can be used with battery charge banks for mobile and off-grid uses.
Also in the flashlight.
Hybrid and electric vehicles.
Flat-screen TVs.
That’s because DC generator provides reliable and efficient energy supply in this usage.

Answer 2

Answer:

•Alternative current:

1) The current whose magnitude changes continuously and direction changes periodically.

2) The source of AC is generator.

3) AC is supplied at 220V.

4) The frequency of AC is 50Hz and current changes it's direction 100 times in 1 second.

•Direct current:

1) The current whose magnitude does not change with time.

2) The source of DC current is cell, battery.

3) The shock of DC is not dangerous.

4) The frequency of DC is 0Hz.
