A.Y : 2021-2022 Class : 1st Year Semester : 1
➢ The over all theory is made into 2 chapters.
➢ These chapters give knowledge of electricity and its basics.
➢ The brief information about each chapter is given below.
Chapter-1: Safety
>> In this chapter the learner will learn about the safety and its importance in workplace. The topics like tools, PPE and
First Aid are part of safety. So at the end of this chapter the leaner must be able to follow the safety procedures for
safe working environment.
Chapter-2: Wiring Installation
>> In this chapter the learner will learn about the basics about electricity. Basic electrical parameters like Resistance,
Voltage, Current , Types of currents and their representation, simple circuit, series circuit, parallel circuit, Ohms law,
power circuit and its types etc are some of the major topics. So at the end of this chapter the leaner must be in a
position to apply this knowledge in electrical installations.
