STEPS IN DETERMINING THE VALUE OF THE COLOR CODED RESISTOR

•Hold the resistor. Look for the 3 colors which they are near on each other. Place it on your left side.

•Look for the 1st color. The first color represents to the 1st significant digit of the resistor.

•Look for the 2nd color. The second color represents to the 2nd significant digit.

•Look for the third color. The third color represents to the number of zeros.

•Look for the 4th color.

It represents to the TOLERANCE of the resistor.
