Color Coding
Electronic components have often their value printed
on the component by color rings, the so-called color code.
Particularly widespread are color coding on resistors.
In order to determine the values you use these tables...
Resistor Color Code
The value of a standard resistor is indicated
on the component with four colored rings.

The fourth color ring indicates the tolerance...
-
Gold: 5% tolerance
-
Silver: 10% tolerance

Ring 1: yellow = 4
Ring 2: violet = 7
Ring 3: red = × 100 = 4700 Ω = 4,7 kΩ
Ring 4: gold = 5% tolerance
