@Felthry I have no idea what this is
I'm gonna guess resistors
@socks yeah, resistor color code. also used for inductors, sometimes, but you don't see those very often
used to be used for certain capacitors too but not anymore

@Felthry I got a few resistors with my Arduino kit and, no joke, I seriously can't tell the colours apart
I'm not colourblind or anything, they're just tiny and some are very similar to each other
@socks (E12 values are the preferred values for 10% resistors and the most common ones available for 5% and 1% ones too, they're
1.0, 1.2, 1.5, 1.8, 2.2, 2.7, 3.3, 3.9, 4.7, 5.6, 6.8, 8.2
of those, the most common ones are the E6 values,
1.0, 1.5, 2.2, 3.3, 4.7, 6.8
which are nominally for 20% tolerance devices
oops now i'm rambling
-F)
@socks E12 actually doesn't quite cover the whole decade since they're rounded to two digits, there's a little gap between 1.2+10% (1.32) and 1.5-10% (1.35)

@socks the general idea is that if you take all the E12 numbers ±10%, that covers an entire decade of values. same goes for the E6 numbers ±20%, and for tighter tolerances there's also E24 and E48 all the way down to E192 for 0.5%
