Question

Suppose the first strip $A$ is red, second strip $B$ is yellow, third strip $C$ is orange and fourth strip $R$ is silver, from left to right, in a colour coded carbon resistor. What is the value of resistance?

• A. $ (24\pm 5\%)\,k\Omega $
• B. $ (24\pm 10\%)\,k\Omega $
• C. $ (350\pm 5\%)\,k\Omega $
• D. $ (350\pm 10\%)\,k\Omega $

Answer 1

Answer: (B)

Value of resistance is expressed as $A B \times 10^{\circ} \pm D$
$\therefore $ Resistance $\rightarrow(24 \pm 10 \%) k \Omega$
