The value of the resistance of a carbon resistor having the standard colour-coding as shown in the figure is n   GΩ ± 5 % . What is the value of n ?

Correct answer

02.10

Step-by-step solution

From colour codes for resistors. R = 21 × 10 8   Ω ± 5 % R = 2 . 1 × 10 9   Ω ± 5 % ⇒ R = 2 . 1   GΩ ± 5 % n = 2 . 1
