- 5 Band resistors and correct orientation 5 answers
I found a pile of these resistors, and I didn't know how to decode them using 4-band logic.
How do you know if it's to be read:
Brown(1), Black(0), Black(0), Black(0), Red(2) = 100Ohm
Red(2), Black(0), Black(0), Black(0), Brown(1) = 200Ohm
Now before you get carried away, I hooked up a multimeter and I know that it is a 200Ohm resistor.
My question is, how would I be able to guarantee it is a 200Ohm resistor and not a 100Ohm resistor, using only the bands?
While looking for a picture to put with this post, it appears "grouping" plays a role on some 5-band resistors, but in this case there appears to be no grouping, but the red band is slightly thicker than the brown band. Is there a standard, or is this some form of tribal knowledge?
