From colour codes for resistors. R=21× 108Ω±5 % R=2.1× 109Ω±5 % ⇒ R=2.1GΩ ±5 % 10n=21

Q. The value of the resistance of a carbon resistor having the standard colour-coding as shown in the figure is $n G Ω \pm 5%$ . What is the value of $10 n$ ?

From colour codes for resistors.
$R = 21 \times 1 0^{8} Ω \pm 5%$
$R = 2.1 \times 1 0^{9} Ω \pm 5%$
$\Rightarrow R = 2.1 G Ω \pm 5%$
$10 n = 21$
