Question

A carbon resistor has following colour code. What is the magnitude of resistance ?(G=Green, O=Orange, Y=Yellow)

• A. 1.64 m$\Omega \pm$ 5 %
• B. 64 k$\Omega \pm$ 10 %
• C. 530 k$\Omega \pm$ 5 %
• D. 5.3 m$\Omega \pm$ 5 %

Answer 1

The correct option is C 530 k$\Omega \pm$ 5 %

Theroretical
$\begin{array}{cccc}\text{G}& \text{O}& \text{Y}& \text{Golden}\\ 5& 3& {10}^4& 5\%\end{array}$
$53\times {10}^4\pm 5\%$
$\begin{array}{c}530\times {10}^3\Omega \pm 5\%\end{array}$
