Transformers: An Introduction

The principle of transformer was explained and demonstrated in 1831 by Michael Faraday. Basically, it is a device used to transfer electrical energy from one circuit to another. A transformer also changes electricity from high to low voltage by using two properties of electricity. There is magnetism placed around the electric circuit of a transformer. So, every time when a magnetic field changes, a voltage is made.

The loss of the transformer greatly disrupts our normal way of living as power is required for almost every activity such as heating, cooking, cooling, sound, light, computation etc. Main reasons for failure of transformers are winding resistance, hysteresis losses, eddy currents, magnetostriction, mechanical losses, and stray losses.

There are various kinds of transformer like current transformer, isolation transformer, power transformer, electric transformer, audio transformer, fly back transformer, high voltage transformer, low voltage transformer, step down transformer, push pull transformer, isolation transformer.

Thanks to the development in the transformer technology, electric transformer has been put into use everywhere. This updated device is used to transfer an alternating current or voltage from on circuit to another by means of electromagnetic induction.
