PHYSICS PROJECT
MADE BY:
39
AIM
To investigate the relation between the ratio of
1. Input and Output voltage.
2. Number of turnings in the secondary coil and primary coil of a self made transformer.
Certificate
This is to certify that this project is an authenticated and benefited work of _______________of class XII-A of K.V., Tagore Garden, New Delhi.
During the course of the project, I found her hardworking with good understanding and a strong urge to learn this work to be useful.
I found her sincere and pain taking and her all the best part in all her future endeavour.

ACKNOWLEDGEMENT
The satisfaction of successful competition of any task would not be complete without the mention of the people who made it possible.
I under sincere thanks of Mr.______, my Physics teacher, who acted as my guide and took great pain to help me in the entire project. I would also like to thank my family and friends for their valuable help and guidance.
PRINCIPLE
Step-down transformer
A Transformer based on the Principle of mutual induction according to this principle, the amount of magnetic flux linked with a coil changing, an e.m.f. is induced in the neighbouring coil, that is, if a varying current is set-up in a circuit induced e.m.f. is produced in the neighbouring circuit. The varying current in a circuit produce varying magnetic flux which induced e.m.f. in the neighbouring circuit.
INTRODUCTION
A transformer is an electric device which is used for changing the A.C. voltages. A transformer is most widely used device in both low and high current circuit. As such transformers are built in an amazing strength of sizes. In electronic measurement and control circuits, transformer size may be so small that it weighs only a few tens of grams where as in high voltage power circuits, it may weigh hundreds of tones. In a transformer, the electrical energy
