Basics of making transformer (part-2)

A transformer transforms voltage and current. But the total electrical input and total energy output is almost same. Some losses are there ( core loss, iron loss etc).

We know that the power is the product of voltage and current(p=v*i).

The relation between primary voltage and secondary voltage is

V1/v2=i2/i1=n1/n2

An actual/theoretical transformer has no loss. But in practical there are several types of losses in transformer. In this page I am dealing with practical transformer making, so we will neglect the loss or take the loss as a predefined constant value.

Basic construction of transformer-

In

General transformers are mainly of two types.

1.Core type

2.shell type

the core of the transformer is mainly made from E and I shape iron plates
