Introduction
In electronics, resistors are an essential component used to control the flow of electrical current. One of the most widely used methods for identifying resistors is the resistor color code system. This system uses a combination of colored bands to indicate the resistance value and tolerance of a resistor. In this article, we will explore the resistor color code system and learn how to convert the color code to a specific resistance value and tolerance.
The Resistor Color Code System
The resistor color code system consists of four to six colored bands, depending on the type of resistor. The first two bands represent the significant figures of the resistance value, the third band represents the multiplier, and the fourth band represents the tolerance. The fifth and sixth bands, if present, represent the temperature coefficient and the reliability level, respectively.
