WHAT IS ELECTRONICS ?

*The branch of engineering in which the flow and control of electrons in vacuum or semiconductor are studied is called electronics.

*Electronics can also be defined as the branch of engineering in which the electronic devices and their utilization are studied.

*The motion of electrons through a conductor gives us electric current. This electric current can be produced with the help of batteries and generators.

*The device which controls the flow of electrons is called electronic device. These devices are the main building blocks of electronic circuits.

*Electronics have various branches include, digital electronics, analog electronics, micro electronics, nanoelectronics, optoelectronics, integrated circuit and semiconductor device.

Welcome to the world of Consumer Electronics Servicing!

This Module is an exploratory course which leads you to Consumer Electronics Servicing National Certificate Level II ( NC II)1. It covers five common competencies that a Grade 7 / Grade 8 Technology and Livelihood Education (TLE) student like you ought to possess, namely:

1) Use Hand Tools;

2) Perform Mensuration and Calculation;

3) Prepare and Interpret Technical Drawings;

4) Practice Occupational Safety and Health; and

5) Maintain Tools and Equipment
