content: Hi,I am sorry for the stupid question.. but I cant see color a lot and at the moment I dont have anyone to help me.Can you tell me the color of the resistors in the photo in the correct order? or if you want the value, unfortunally I cant see colors very well and the fact that these resistors have been cooked doesn't help.Thank you so much

content: I'ld interpret the brown wider ring on both resistors as the indicator for tolerance (1%).So the upper resistor would read brown-blue-green-yellow(orange?) = 1.65MOhm (165kOhm?)The lower one is green-brown-brown-brown = 5.11kOhm

content: Quote from: TurboTom on March 19, 2023, 03:02:22 pmThis Is the only reasonable answer, because ai can't Imagine a 165 Meg resistors in a 1/8w format.Meanwhile my girlfriend returned home, and She neither can understand if it's orange or Yellow..

content: I think it's orange. Or my LCD thinks so, whateverThat's 165kΩ 1% or 135MΩ 1%, so definitely 165kΩ it is. Or maybe 1.65MΩ 1% if yellow, not orange.The second resistor is 5110Ω 1% or 1110Ω 0.5%. Probably the former.Look for other resistors on the same board to find other example of orange and yellow for comparison. Again, I think it's 165k.See if the chip's datasheet specifies any typical values, perhaps?

content: Is this part of a power supply? If you can trace which pin of AN8032 this resistor divider is connected to then look at the schematic in the datasheet and the pin voltages required. Based on that and based on the rail voltages you can calculate the resistor divider ratio, and from there determine which of the resistors values people suggested in this thread make sense.

content: I'd vote for orange too.If it was yellow it would have been much lighter given the green and blue are somewhat faded too.You might still be able to measure them.
