What numerical value does red represent in resistor color coding?

In the resistor color code system, the color red is assigned a numerical value of 2. This system uses a series of colors to represent numbers from 0 to 9, which are used to indicate the resistance values of resistors. Each color corresponds to a specific digit, and red is one of the commonly used colors.

When reading a resistor, you typically encounter a sequence of colored bands. The first two bands represent significant digits, while the third band indicates the multiplier. In this case, the presence of red signifies that the number "2" is being represented. Understanding this coding system is crucial for correctly interpreting the values of resistors in circuits.
