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

Options

  1. A47kΩ,1047kΩ, 10%
  2. B4.7kΩ,54 .7 kΩ, 5%
  3. C470kΩ,5470kΩ, 5%
  4. D470Ω,5470Ω, 5 %

Correct answer

D. 470Ω,5470Ω, 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 - 44

violet - 77

brown - 11

gold - 55 %

R=47×101±5R = 47 \times {10}^{1} \pm 5 %

R=470Ω,5R = 470Ω, 5 %
