A resistor with the bands green, black, and black has a resistance of how many ohms?

To determine the resistance of a resistor based on its color bands, we use the resistor color code chart. The first band represents the first significant figure, the second band represents the second significant figure, and the third band indicates the multiplier.

In this case:

• The first band is green, which corresponds to the number 5.

• The second band is black, which corresponds to the number 0.

• The third band is also black, which indicates a multiplier of 1 (i.e., no multiplication).

Putting this together, the first two bands give us the digits "50." Since the multiplier is 1 (from the black band), we multiply 50 by 1, resulting in a final resistance of 50 ohms.

This reasoning confirms that the correct resistance value for the given color bands is indeed 50 ohms.
