Q. The value of the resistance of a carbon resistor having the standard colour-coding as shown in the figure is $nG\Omega \pm5\%$ . What is the value of $10n$ ?
Question

Solution:

From colour codes for resistors.
$R=21\times 10^{8}\Omega\pm5\%$
$R=2.1\times 10^{9}\Omega\pm5\%$
$\Rightarrow R=2.1G\Omega \pm5\%$
$10n=21$
