240 kΩ resistor colour code

Four bands: Red · Yellow · Yellow · Gold. The first two give the digits, the third multiplies, the fourth states how far off the real part may be.

228 kΩ – 252 kΩ

A gold band allows this much drift.

Band by band

Band	Colour	Meaning
1	Red	1st digit — 2
2	Yellow	2nd digit — 4
3	Yellow	Multiplier — ×10 k
4	Gold	Tolerance — ±5%

The same value on a five-band part

Precision resistors carry three significant digits instead of two, so the same 240 kΩ looks different.
