Second part is about "Transformers And Magnetic Circuits"

For the "Magnetic circuits", we will learn the following:

In this course we will discuss:

  1. Importance of the magnetic circuit and its application like transformer.

  2. Difference between linear and non linear materials.

  3. Important definitions of magnetic circuits, flux linkage and reluctance.

  4. Analogy between the magnetic and electric circuits , the similarity between them like resistance, reluctance, conductivity, permeability, EMF, MMF, current, flux, magnetic flux density and current density.

  5. Induced EMF , fringing effect and ampere right hand rule or screw rule.

We will take 3 examples on the magnetic circuits to make it clear for you.

For the "Transformers", we will learn the following:

In this course we will discuss:

  1. Importance of transformers and why it is considered as the Backbone of the Power System.

  2. In this course we will discuss the construction of the transformer and its Main Components as 

  3. Iron Core which is responsible for the magnetic flux action.
