What Replaces An AC Generator To DC Generator?

by | Last updated on January 24, 2024

, , , ,

New AC generator uses concave magnets, changes them, and lastly removes the coil and replaces it with an armature instead. The AC generator will start functioning as a DC generator. Hence, (A) is the correct option. So, if we want to convert an AC generator to a DC generator we must use a

split ring type commutator

.

What changes from AC generator to DC generator?

Answer Expert Verified

The

slip rings used in the AC generator can be removed and split rings can be replaced

instead. Now, AC generator uses concave magnets, change them and lastly remove the coil and replace it with armature instead. The AC generator will start functioning as a DC generator.

What change should be made in AC generator so that it may become a DC generator?

By

replacing the slip rings of an A.C. generator by

a commutator, we can convert it into a D.C. generator.

What should be done to change the generator to DC?

Answer: To convert A C generator to D C generator you must

replace the slip rings with split ring

.

What is another term for a DC generator?


A dynamo

is an electrical generator that creates direct current using a commutator.

What part of a DC generator converts AC to DC?


The commutator

on the DC generator converts the AC into pulsating DC. The commutator assures that the current from the generator always flows in one direction.

How do DC generators work?

A DC generator operates

on the principle of Faraday's laws of electromagnetic induction

. According to Faraday's law, whenever a conductor is placed in a fluctuating magnetic field (or when a conductor is moved in a magnetic field) an EMF is induced in the conductor. … Z- Total number of armature conductors in the field.

What is function of brushes in electric generator?

Brushes are used

to conduct current

in the electric generator, be it either AC generator or DC generator. 3. In DC generators, they collects Direct current. And conducts current for the electric generator forming the circuit from commutator to external circuit.

What is the working 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 magnetic field will interfere with the electrons in the conductor to induce a flow of electric current inside it.

What is the major difference between the simple alternator and most practical alternators?

Simple alternator Most practical alternator In a simple alternator, small voltage is produced. In a most practical alternator, large voltage is produced It is used in cars and bicycles as dynamos. It is used in power houses.

What type of current does a generator produce?

What are generators? Generators are machines that produce electric energy in the form of voltage and current. They produce electricity based on the principle of electromagnetic induction. There are two fundamental types of generators known as

AC (alternating current)

and DC (direct current) generators.

Which one of the following changes will increase EMF in a simple generator except?

Each one of the following changes will increase emf (or voltage) in a simple generator except

increasing the number of turns in the armature coil

.

winding the coil on a soft iron armature

.

increasing the size of the gap in which

the armature turns.

How can you increase the power of an electric motor?

Clearly, the power of a DC motor depends on

the torque of the coil

. Since torque depends on the current and the area of the coil. Also, the magnetic field can be increased by adding a soft iron core.

Is dynamo and generator same?

Dynamo – a device that makes direct current electric power using electromagnetism. It is also known as a

generator

, however the term generator normally refers to an “alternator” which creates alternating current power.

Why is it called DC generator?

A DC generator or direct current generator is one kind of electrical machine, and the main function of this machine is

to convert mechanical energy into DC (direct current) electricity

. The energy alteration process uses the principle of energetically induced electromotive force.

Where are DC generators used?

They are used as portable generators where low power supply is required. They are used in

motorcycles as dynamos

, in toys such as remote control cars and in appliances such as electric shavers. These generators find uses in arc welding in which huge drop in voltage and constant current are required.
