Complete Guide on Transformers

Make your Electrical Transformer concepts crystal clear! Learn everything about Transformer in easiest way!

Course Introduction

Transformers are probably one of the most useful invention in electrical engineering. Transformer can raise or lower voltage in AC circuits, it can also isolate one circuit from another. Not only this, but because of transformer only, we could transmit power over a long distance and distribute it safely to factories or homes. But, what is transformer? How it works ? How it is constructed? What are the different types. All the details about the transformer we are going to learn in this course.

We cannot imagine power system without transformer. Transmission of electricity over such a long distance is only possible because of transformer. And hence, if you are an electrical engineer, you must know about the transformer. Its not an optional thing to know but, a mandatory one! You are not just learning any other device but, the most important equipment in the whole electrical engineering.

Now, if you think, concepts of transformer are difficult to understand, then this course will prove you wrong. By the end of this course, you will not only understand the transformer clearly but also, you’ll develop an interest in electrical machines. The course in designed and organised in such a way that, it unfolded every concepts at the right time which makes understanding very very easy and interesting.

" The primary focus of this course is to clear the transformer related concepts. "
