Resistors are ubiquitous components in electrical circuits, controlling the flow of current and voltage. Understanding their values is crucial for proper circuit design and troubleshooting. One of the most common resistor types is the 100 ohm resistor, identified by its color code. This comprehensive guide will provide a meticulous understanding of the 100 ohm resistor color code, empowering you to decipher its value like a pro.
Resistors are adorned with colored bands, each representing a specific value. The color code follows a standardized convention, ensuring universal identification. The initial bands indicate the resistor's value, followed by a multiplier band and optional tolerance band.
For 100 ohm resistors, the color code is as follows:
Result: 10 x 1,000 = 100 ohms
The resistor color code encompasses a wide array of colors, each assigned a specific numerical value:
Band Color | Numerical Value |
---|---|
Black | 0 |
Brown | 1 |
Red | 2 |
Orange | 3 |
Yellow | 4 |
Green | 5 |
Blue | 6 |
Violet | 7 |
Gray | 8 |
White | 9 |
Gold | 0.1 (5%) |
Silver | 0.01 (10%) |
Multiplier bands indicate the number of zeros to be appended to the value represented by the first two bands. Common multiplier band colors and their respective values are:
Band Color | Multiplier |
---|---|
Black | x1 |
Brown | x10 |
Red | x100 |
Orange | x1,000 |
Yellow | x10,000 |
Green | x100,000 |
Blue | x1,000,000 |
Violet | x10,000,000 |
Tolerance bands provide information about the resistor's allowable deviation from its nominal value. The most common tolerance levels are:
Band Color | Tolerance |
---|---|
Gold | ±5% |
Silver | ±10% |
