Question

What is dynamo? How it works? Working principal of dynamo?

Answer 1

Answer:

Pls mark as brainliest and follow me ❤️

Explanation:

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

Dynamos and Generators convert mechanical rotation into electric power. 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.

Principle : Generator works on the principle of electromagnetic induction. Whenever the magnetic field linked with a coil changes , an induced emf is setup in coil.

Answer 2

Answer:Dynamo is an electricAL generator that creates direct current using a commutator

Explanation:

Principle : Generator works on the principle of electromagnetic induction.

Whenever the magnetic field linked with a coil changes , an induced emf is setup in coil.

Working:

1. when armature rotates with its axis perpendicular to magnetic field , the magnetic flux linking to the coil changes and an emf is induced in the coil. Therefore an induced current flows in the coil and in the external circuit connected to the coil through brushes and the slip rings.

2, The plane of coil rotates such that the arm AD goes down the plane of paper, and the arm BC becomes above the plane of paper.

3. Using Fleming's Right hand rule, we find that the current flows in the direction of CBAD and in the outer circle from Brush B2 To B1.
