An AC generator is
a machine that converts mechanical energy into electrical energy
, generated as an alternating current sinusoidal output waveform. … AC generators are also known as alternators, and are classified according to their rotor construction.
What is AC generator explain with diagram?
AC generator is
a machine that converts mechanical energy into electrical energy
. … AC generators work on the principle of Faraday’s law of electromagnetic induction, which states that electromotive force – EMF or voltage – is generated in a current-carrying conductor that cuts a uniform magnetic field.
What are AC generators?
An AC generator is
a machine that converts mechanical energy into electrical energy
, generated as an alternating current sinusoidal output waveform. … AC generators are also known as alternators, and are classified according to their rotor construction.
What is AC generator and its types?
As previously discussed, there are two types of AC generators:
the stationary field, rotating armature; and the rotating field, stationary armature
. … The rotating field, stationary armature type AC generator is used when large power generation is involved.
What is AC generator short answer?
Ac generator is
a machine that converts mechanical energy into electrical energy
. Complete answer: AC generators work on the principle of Faraday’s law of electromagnetic induction. This law states that electro motive force is generated in a current carrying loop that is placed in a uniform magnetic field.
What are the 2 types of generator?
There are two fundamental types of generators known as
AC (alternating current) and DC (direct current) generators
. While the technique of producing electricity is the same in both types, AC and DC power become different in terms of their applications – the way in which loads receive electric power.
What is the principle of generator?
Electric generators work on the principle of
electromagnetic induction
. A conductor coil (a copper coil tightly wound onto a metal core) is rotated rapidly between the poles of a horseshoe type magnet. The conductor coil along with its core is known as an armature.
What are the two main parts of an AC generator?
There are two main components in the generator,
the rotor and the stator
. The generator must also have a source of DC current to magnetize the rotor, called the exciter.
What is the principle of motor and generator?
The
motor uses electricity
. It works on the principle that when a current-carrying conductor is placed in a magnetic field, it experiences a force and rotates. The word ‘generator’ means to generate something, and an electrical generator produces (generates) electricity.
What is AC generator used for?
Ans: The Uses of AC Generators are a Pervasive Component in Many Applications Such as, In automobiles, where they are known as
alternators
.
power generation from windmills
.
power generation from hydro-electric dams
.
Is a generator AC or DC?
| Alternating Current (AC) and Direct Current (DC) Electric Generator | The Electric Motor Electromagnetic Induction |
|---|
Which is better AC or DC generator?
AC generators are very efficient
as the energy losses are less. Due to sparking and other losses like copper, eddy current, mechanical, and hysteresis losses DC generators are less efficient. In an AC generator, the electrical current reverses direction periodically.
How does a simple AC generator work?
An alternating current (ac) generator is a device that produces a potential difference . A simple ac generator consists of a
coil of wire rotating in a magnetic field
. Cars use a type of ac generator called an alternator to keep the battery charged and to run the electrical system while the engine is working.
Is commutator present in AC generator?
No commutator is present in AC Generator
. To make the current flow in one direction only, DC Generator comprises the commutator.
Which is not present in AC generator?
The general A.C. generator has all the listed components except
the commutator
.
What is motional emf?
An emf induced by motion relative to a magnetic field is called a motional emf. This is represented by the
equation emf = LvB
, where L is length of the object moving at speed v relative to the strength of the magnetic field B.
