Question

The colour code of a resistance is given below i.e., yellow, violet, brown, and gold. The values of resistance and tolerance respectively are:

• A. $47\Omega \pm 5\%$
• B. $4.7k\Omega \pm 5\%$
• C. $470\Omega \pm 5\%$
• D. $470k\Omega \pm 5\%$
  

Answer 1

The correct option is C $470\Omega \pm 5\%$

According to colour coding,

$\text{Yellow}=4;\text{violet}=7\text{Brown}=1;\text{gold}=5\%\text{(tolerance)}$

$\therefore R=47\times {10}^1\pm 5\%\Omega \text{(or)}$

$=470\Omega \pm 5\%$
