Resistor

Resistors

Resistors are electronic components that serves to set or keep the current flowing strong. The units are ohm resistor (Ω).


Fixed ResistorsFixed resistor is the resistor resistance value is not changing, and the amount of prisoners who had symbolized by the color of a circle located throughout the body. Fixed resistors are generally made of carbon materials. Fixed resistors consist of two types namely kesil resistors with power, and resistors with a large power.
Resistors are helpless little resistance values symbolized by the color code, while having great power symbolized by the numbers.

Example:

4 Color
Ring 1 = Orange
Ring 2 = Red
Ring 3 = Yellow
Ring 4 = Gold
So the summary is:
 R = 320000Ω = 320kΩ / 5%

5 Color
Ring 1 = Red
Ring 2 = Red
Ring 3 = Black
Ring 4 = Red
Ring 5 = Chocolate
So the summary is:
R = 22000Ω = 22kΩ / 1%

Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in most electronic equipment.
