Default How do they paint the stripes on resistors, bumble bee caps, etc?

To measure the BV[ break down voltage] of a diode you apply a small
current [5 micro amp] and measure the voltage.
If it is a high voltage it is in one polarity. If a low voltage it is
the forward direction. If correct the diode drops down. If not it goes
thru a tube that rotates i it n the correction direction and into the
hopper for the painter..
