Question

The color code of a carbon resistor is given below

The resistance of the resistor will be

• A. $24\times {10}^7\Omega \pm 10\%$
• B. $25\times {10}^4\Omega \pm 10\%$
• C. $35\times {10}^6\Omega \pm 5\%$
• D. $27\times {10}^5\Omega \pm 5\%$

Answer 1

The correct option is A $24\times {10}^7\Omega \pm 10\%$

From the colour coding of carbon resistor
Red $\to$ Digit $\to 2$
Yellow $\to$ Digit $\to 4$
Violet $\to$ Multiplier $\to {10}^7$
Silver $\to$ tolerance $\to 10\%$
therefore $R=24\times {10}^7\Omega \pm 10\%$
