I. INTRODUCTION Your Technology & Livelihood Education (TLE) subject has four areas: Information and Communication Technoloy (ICT), Home Economics (HE), AgriFishery Arts (AFA) and Industrial Arts (IA). Consumer Electronics is a course under Industrial Arts.

Electronics is a branch of physics that deals with the behavior and controlled flow of electrons. Have you ever been curious about what is inside an FM radio box? Will you be able to identify the components present inside that box? So many small components inside that box. The voltage commonly used in home appliances is 220V (It
