Which color band signifies a resistor with a multiplier of 100,000,000?

The color band that signifies a resistor with a multiplier of 100,000,000 is gray. In the resistor color code, each color corresponds to a specific number, and the multipliers are defined by the same color code.

The number 100,000,000 can be expressed in scientific notation as 10^8. According to the resistor color code, gray represents the number '8'. Therefore, when gray is used as a multiplier in a resistor's color bands, it indicates that you multiply the base number (given by the first two color bands) by 10 raised to the power of 8, or 100,000,000.

This understanding of the color code allows technicians to identify and calculate the resistance values accurately, which is essential in various electronic applications.
