Question

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

• A. 470 $k\Omega,5\%$
• B. 47 $k\Omega,10\%$
• C. 4.7 $k\Omega,5\%$
• D. 470 $\Omega,5\%$

Answer 1

Answer: (D)

470 $\Omega,5\%$

Answer 2

From colour coding information for electric resistances, we have
$\begin{matrix}{\text{Yellow}}&{\text{Violet}}&{\text{Brown}}&{\text{Gold}}\\\ 4&7&1&5\%\end{matrix}$
So, $R=47 \times 10^{1} \pm\,5\%$
$R=470\,\Omega\,\pm\,5\%$
