What is the value of the first digit for a resistor with a green band?

The value of the first digit for a resistor with a green band is 5. This is based on the color coding system used for resistors, where each color corresponds to a specific numerical value. The green band is designated as the number 5 in this system.

When identifying resistors, it's essential to read the colors accurately, as they determine the resistance value and tolerance. The first digit is crucial because it significantly influences the overall resistance offered by the resistor in a circuit. Understanding how to interpret these color codes is fundamental for technicians working with electronic components, ensuring they select the correct resistor for their applications.
