Study Notes
Resistor Color Code
- Resistors use color bands to indicate their resistance value.
- The color bands provide a standardized way to read the resistance of a resistor.
- Different colors represent different numerical values.
- The first two bands represent the first two digits of the resistance value.
- The third band represents the multiplier.
- The fourth band indicates the tolerance.
Color Codes
- Black: 0
- Brown: 1
- Red: 2
- Orange: 3
- Yellow: 4
- Green: 5
- Blue: 6
- Violet: 7
- Gray: 8
- White: 9
- Gold: 0.1
- Silver: 0.01
- No fourth band: ±20%
- Gold fourth band: ±5%
- Silver fourth band: ±10%
How to Read Resistor Color Codes
- Hold the resistor so the tolerance band is on your right.
- Start from the left, and identify the bands' colors.
- Translate the colors into digits.
- The band immediately next to the tolerance band is the multiplier.
- Multiply the first two digits by 10multiplier.
- Add the tolerance to the resulting figure.
4-Band Resistor
- The first two bands indicate the first two digits.
- The third band is the multiplier.
- The fourth band represents the tolerance.
5-Band Resistor
- The first three bands represent the first three digits.
- The fourth band gives the multiplier.
- The fifth band marks the tolerance.
Example Resistor
- A resistor with blue, white, and black bands represents a 69Ω resistor.
Tolerance
- Tolerance represents the acceptable deviation from the nominal resistance.
- The tolerance value is used to ensure that the actual resistor value is within the expected range.
