Question

In the figure a carbon resistor has bands of different colours on its body as mentioned in the figure. The value of the resistance is}

• A. $2.2\mathrm{k}\Omega$
• B. $3.3\mathrm{k}\Omega$
• C. $5.6\mathrm{k}\Omega$
• D. $9.1\mathrm{k}\Omega$

Hint:

Colour code: Black(0), Brown(1), Red(2), Orange(3), Yellow(4), Green(5), Blue(6), Violet(7), Grey(8), White(9).

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Colour code: Black(0), Brown(1), Red(2), Orange(3), Yellow(4), Green(5), Blue(6), Violet(7), Grey(8), White(9).
Step 2: Detailed Explanation:
The colour bands are White, Brown, Red, Silver. White = 9, Brown = 1, Red = $10^2$, Silver = $\pm 10%$. So resistance = $91 \times 10^2 = 9100\Omega = 9.1\mathrm{k}\Omega$.
Step 3: Final Answer:
The resistance is $9.1\mathrm{k}\Omega$.
