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 $AB\times 10^{\circ }\pm D$
$\therefore$ Resistance $\to (24\pm 10\%)k\Omega$
