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

1. 47 kΩ, 10%
2. 4.7 kΩ, 5%
3. 470 Ω, 5%
4. 470 kΩ, 5%

Correct answer: 470 Ω, 5%

Solution

The color code corresponds to 470 Ω with a tolerance of 5%. This is determined by interpreting the bands according to the standard resistor color code chart.
