Answer is Right!
Answer is Wrong!
The correct answer is: C. 2
The first band of a resistor color code indicates the first digit of the resistance value. The second band indicates the second digit of the resistance value. The third band indicates the number of zeros to multiply the first two digits by. The fourth band indicates the tolerance of the resistance value.
The color blue corresponds to the number 2. Therefore, a resistor with a blue band as its first band has a resistance value of 2.
The other options are incorrect because they do not correspond to the color blue.
