DESIGN AND CONSTRUCTION OF CAR TOUCH INTRUDER ALARM

CHAPTER ONE 1.0  INTRODUCTION A transformer is a magnetically coupled coil used in transmission of an electric power. This coil may be electrically link, but not electrically linked as in two winding transformer. It consists of primary winding and secondary winding which the number of turns varies depending on the type of transformer. Transformers are operated by the principle of mutual inductance between two separate coils wound on the same core. ...
