10k resistor color code
Brown, black, orange, gold: that is 10 kΩ on four bands. The 1 and the 0 make 10, and orange enters as ×1,000. On five bands the same part reads brown, black, black, red, brown. This page compares the two formats and shows how far the measured value may stray from 10,000 Ω.
10 × 1,000 = 10,000 Ω, with a window of 9,500 to 10,500 Ω.
100 × 100 = 10,000 Ω, with a window of 9,900 to 10,100 Ω.
Silver widens the window to 9,000 to 11,000 Ω.
Swapping orange for yellow moves the multiplier to ×10,000: 10 × 10,000 = 100 kΩ.
With red (×100): 10 × 100 = 1,000 Ω.
Typing 10k into the calculator returns brown, black, orange and gold.
Start from the end opposite the tolerance band. The tolerance band is usually gold or silver (or visibly set apart from the rest with a wider gap), so it's always read last, and tells you which end to begin at.
Brown, black, orange and a tolerance (gold, ±5%) on four bands. On five bands, brown, black, black, red and brown.
Only the multiplier: orange for 10k and yellow for 100k. Brown and black stay the same in both.
Anything from 9,500 Ω to 10,500 Ω. At ±1%, the range narrows to 9,900 Ω to 10,100 Ω.
The nominal value is the same, 10 kΩ. What changes is the marking format and, usually, the tolerance, which is often tighter on five-band parts.
This is a standard E24 value (typical tolerance ±5%).
