Semi-Detailed Lesson Plan in TLE-Electrical/Electronics
Color Code is a system of colors used to to indicate the resistance resistance value of Concept: Resistor Color resistors that uses colored stripes or bands printed on its body. body.
Value Concept: Color plays a vitally important role in the world in which we live. Color can be a form of communication. Color can sway thinking, change actions, and cause reactions.
I. Objecties: At the end of the lesson, the students expected to: 1. dentify the colors of resistor color coding accordingly. !. Calculate the value of resistors based on the color code. ". Adhere to the importance of using color. II. Subject !atter: Resistor Color Coding A.
