How to Read Resistor Color Codes

A 4-band resistor uses colored bands to indicate its resistance value. The first two bands represent significant digits, the third band is the multiplier, and the fourth band indicates tolerance. Hold the resistor with the tolerance band (gold, silver, or gap) on the right.

For example, Brown-Black-Orange-Gold reads as 10 × 1,000 = 10,000 Ω (10 kΩ) with ±5% tolerance, meaning the actual value is between 9,500 Ω and 10,500 Ω.
