Question

What is an electrical transformer? Discuss basic principles of operation and applications of electrical transformers. Can you relate electromagnetic induction to the operation a transformer?

Answer 1

Electrical transformer is the static Electrical device which step up and step down the volatge or current without changing the frequency and power .

Principles of operation: When you apply the AC sinusoidal input voltage to the transformer it will creat flux in transformer due to the induction effect which having sinusoidal nature and it will flow through the core of the transformer and in the secondary side of transformer same flux produced voltage in step up and step down form.

The application of electrElec transformer is at power station to step up volatge to transmit the high power and it is also use as the distribution transformer to distribute the electricity at homes . In electronics devices also it is use to step down the boltage at 12v to Operate the electronics deviede like mobile charger etc.

You can relate the electromagnetic induction becubec when flux produced by the primary voltage of transformer the core will magnetiz and to that magnetism or flux produced the secondary volatge .
