The colour code of a resistance is given below The values of resistance and tolerance, respectively, are

Options

  1. A47   kΩ ,   10 %
  2. B4 .7   kΩ ,   5 %
  3. C470   kΩ ,   5 %
  4. D470   Ω ,   5 %

Correct answer

D. 470   Ω ,   5 %

Step-by-step solution

The colours brown, red, green, blue, and violet are used to give value of resistance while golden strip is for tolerance. yellow - 4 violet - 7 brown - 1 gold - 5 % R = 47 × 10 1 ± 5 % R = 470   Ω , 5 %
