Resistance of Yellow Violet Orange Silver 4 Band Resistor
A resistor having color coding:
Yellow Violet Orange Silver will have resistance:
- 4.7 kΩ ± 10%
- 47 kΩ ± 10%
- 2.7 kΩ ± 10%
- 27 kΩ ± 10%
Correct answer: 2. 47 kΩ ± 10%
Explanation:
Yellow, Violet = 47
Orange = 10^3
Silver = ±10% tolerance
