PROCEDURES:

TEACHER’S ACTIVITY A. Classroom Routine Opening Prayer  Greetings  Checking of Attendance 

STUDENT’S ACTIVITY

B. Review/Recall Let us have a recall about the  previous topic: What are the types of resistors?  



Ok very good, I’m very glad that you’ve still remember our previous lesson. So let’s now proceed?

C. Motivation Showing of the Philippine Flag.  Do you know what the color o f  Philippine flag stand for? So, what is the me aning of blue?  Very good! How about the red? Very good again. 

Do you know that, not only the Philippine flag has colors and meaning, resistors has colors and meaning too.



 



The types of resistors are: a. wire –wound resistor b. carbon composition resistor c. SMD resistor d. variable resistor

“Yes sir”

“Yes sir” is the symbol for peace, truth and  justice.

is the symbol for patriotism and valor.

D. Activity Directions: Answer the following: 



Identify the color of the resistor below

RED – BLUE – YELLOW – GOLD

Question: How can we use color in identifying the value of resistor?

By using resistor color coding chart.

Self – exercises What is the numeric value of yellow? 

4



The value of green.

5



Color with the value of zero.

Black

Color that represent the value of two (2)

Red



Question: How to read the color value in  resistor body? 



By following procedure in interpreting resistor Color Codes.

Procedures in interpreting resistor color codes. Answering self-check.

E. Analysis Can you identify the colors in the color code table that the resistance of carbon resistors made of? What are those?

How can we find the first color in the resistors body? F.

-

Yes sir

-

They are black, brown, red, orange, yellow, green, blue, violet, gray, and, white.

-

The color closer to the edge of the body.

-

I learned that by following the procedures in resistor color coding, we will easily determine the resistance or the color code value of carbon resistors.

-

As a student taking electronics it is very helpful knowing a resistor color coding because it will help a lot in project making as well as in troubleshooting.

Abstraction What have you learned?

For you as a student taking consumer electronics servicing, hoe is it important to know the resistor color coding?

G. Application GROUP ACTIVITY ACTUAL COLOR CODING The class will be divided into four groups. Each group will be given a tabulation form and five assorted resistors.

IV.

EVALUATION Determine the color code of the following: 1. RED WHITE ORANGE SILVER 2. BROWN BLACK RED GOLD 3. ORANGE ORANGE BLACK NO COLOR 4. YELLOW VIOLET YELLOW GOLD 5. BLUE RED GREEN SILVER

V.

ASSIGNMENT Bring an Ohmmeter and five assorted re sistors for measuring resistance.
