4-bands 4k7 Resistor color code is as follows with four bands:
4k7 Resistor color code:
[Yellow, Violet, Red, Gold]
| Band | Color | Value |
|---|---|---|
| 1st Yellow |  | 4 |
| 2nd Violet |  | 7 |
| 3rd Red |  | 100 |
| 4th gold |  | +-5% |
| 1st digit 4 2nd digit 7 3rd multiplier: 10 | 4.7k Ohm tolerance: +-5% |
It is calculated as:
(If you want to obtain the value of any resistor on your own then you must check this link of calculating resistor by color code in details. After reading this article you could be able to find any resistor value of your own.)
1st band= Yellow= 4(1st digit)
2nd band= Violet= 7(2nd digit)
3rd band= Red= 100(multiplier)
4th band= Gold= ±5%(tolerance)
Therefore, 47×100±5% ==> 4700Ω ==> 4.7kΩ
And tolerance considered as ==> 5%of4700 ==>235Ω
Final assumed values of 4.7kΩ resistor is between 4465 to 4935Ω
Caution:
If resistor contains Red and Brown color bands then take it properly, as red and brown are very similar when it is already placed in a circuit or it is a used resistor.

Other methods to calculate 4.7kΩ resistor value:
Take the use of digital meter to read the value of a resistor. This is the best method. But digital multi-meter makes the wrong values when a resistor is on circuit, in such circumstances color code is necessary.
