content: Sometimes part-makers paint it as if they want to confuse everybody.One painted ring has to be closer to the end than another, or one (the last) ring has to be far from the all others - but not at this photo.Sometimes there is a presision code ring (or something else), this confuses too.The only help is that some colors usually are used only at the end (gold, silver), but not at the begin.I maybe wrong, but it seems to me this resistor is pictured at it's natural order.

content: If the first ring, the "orange" is orange then it could be 1.8Ohm.Calc like this:1. ring - orange = 32. ring - blue = 63. ring - gray = 84. ring (is the multipler) - gold = 0.1Result: 368^0.1 = ~ 1.8Ohm.Maybe I'm wrong...Let's see what other say.

content: Quote from: Chriss on July 27, 2020, 10:51:21 amYes you are. Multiplier can only be a power of 10, gold = 10-1= 0.1. You cannot apply power to a value directly. 5th ring on such resistors is usually is a manufacturer specific mark of a resistor type.

content: Quote from: Chriss on July 27, 2020, 10:51:21 amThat's, um, certainly the mostcreativeinterpretation of a resistor color code I've ever encountered!The multiplier is amultiplier, not apower. For black through white, it's literally just the number of zeros to append. (E.g. red multiplier -> red=2 -> append 2 zeros.)Quote from: wraper on July 27, 2020, 10:56:11 amExactly!

content: Quote from: wraper on July 27, 2020, 10:41:01 amHello,The black (sometimes also white) ring is usually for a flame proof fusible resistor.(in the input cirquitry of a switchmode power supply).so not to ignore.with best regardsAndreas
