What is the first digit value for the yellow resistor band?

• A. 2
• B. 4
• C. 8
• D. 3

Answer: (B)

The first digit value represented by the yellow band on a resistor is 4. In the color coding system used for resistors, colors correspond to specific numerical values. Each color is assigned a digit from 0 to 9. In this system, the color yellow corresponds to the number 4. Therefore, when determining the value of a resistor with a yellow band, the first significant digit would be 4. This understanding is critical for identifying resistor values accurately in electronic circuits and performing calculations based on those values.
