ACKNOWLEDGMENT

I would like to express my special thanks of


gratitude to my Physics Teacher- Mr.Kanhaiya Jha
as well as our Principal Dr.Fr.joshua who gave me
the golden opportunity to do this wonderful
investigatory project on the topic-"To investigate
the relation between the ratio of
(i) Output and input voltage and
(ii) Number of turns in the secondary coil and
primary coil of aself-designed transformer."
Through this project, I came to know about so
many new things and also helped me in
improving my research skills. I am really thankful
to them.
