If a resistor is 64 ohms, what are the colors of its first three bands?

To determine the color bands on a resistor for a value of 64 ohms, we need to use the standard color code for resistors. The first two bands represent significant digits, while the third band indicates the multiplier.

For 64 ohms, the significant digits are 6 and 4. The corresponding colors for these digits in the resistor color code are:

• 6 is represented by the color blue.

• 4 is represented by the color yellow.

The third band represents the multiplier, which for 64 ohms requires a multiplier of 1 (since 64 can be expressed as 64 x 1). The multiplier of 1 is represented by the color black.

Thus, the colors for a resistor of 64 ohms, using the first three bands, are blue (for 6), yellow (for 4), and black (for the multiplier).

This aligns with the answer choice that correctly reflects these color associations.
