NEET 2020 Physics Resistors and Color Code MCQ Question

The color code for a resistor typically consists of three bands that indicate the significant digits and a multiplier, followed by a tolerance band. In this case, the first two bands represent the digits '4' and '7', giving us '47', and the third band is a multiplier of '1' (10^1), resulting in a total resistance of 470 Ω. The tolerance of 5% indicates the permissible variation in resistance, confirming that option (B) is correct.
