Question

The color code of a resistance is given below : The values of resistance and tolerance, respectively, are :

• A. 470 $k\Omega,5\%$
• B. 47 $k\Omega,10\%$
• C. 4.7 $k\Omega,5\%$
• D. 470 $\Omega,5\%$

Answer 1

The Correct Option is D

To determine the value of resistance and its tolerance using the color code provided, we will interpret the colors on the resistor:

From the image, the color bands are: 

• Yellow
• Violet
• Brown
• Gold

According to the resistor color code:

Color	Digit	Multiplier	Tolerance
Black	0	× 1	-
Brown	1	× 10	1%
Red	2	× 100	2%
Orange	3	× 1,000	-
Yellow	4	× 10,000	-
Green	5	× 100,000	0.5%
Blue	6	× 1,000,000	0.25%
Violet	7	× 10,000,000	0.1%
Gray	8	× 100,000,000	0.05%
White	9	× 1,000,000,000	-
Gold	-	× 0.1	5%
Silver	-	× 0.01	10%

The value of the resistor can be calculated as follows:

1. First Band (Yellow): 4
2. Second Band (Violet): 7
3. Third Band (Brown multiplier): × 10
4. Fourth Band (Gold tolerance): 5%

Thus, the resistance value is calculated as:

\(47 \times 10 = 470 \Omega\)

The tolerance is \(5\%\).

Therefore, the corrected resistance value and tolerance are 470 \(\Omega, 5\%\), which matches the correct answer option.
