MCQ
Identify the wrong statement describing the color code for carbon resistors.
  • A
    The first band indicates the first significant figure.
  • B
    The second band indicates the second significant figure.
  • ✓
    The third band indicates the third significant figure.
  • D
    The fourth band indicates the possible variation in the percent of the indicated value.
✓

Answer

Correct option: C.
The third band indicates the third significant figure.

The third band indicates the power of ten with which the first and second significant figures must be multiplied to get the resistance value in ohms. All the other statements are valid.
