Note: 1% resistors read a bit differently than 5% resistors. For example a 10K
ohm resistor in the 5% method would be Brown for 1, black for 0, orange for 3
places after the last defined digit, and then gold to identify the part as a 5%
component. So 1-0-000 ohms +-5%.
A 1% 10.0K resistor needs to identify one more place of precision than a 5%
resistor does, so it includes an extra stripe. In this case it would be brown for
1, black for 0, another black for another 0, red for two remaining zeros, and a
brown to indicate 1%. So 1-0-0-00 +-1%. It is easy to mix up what end is what
on these resistors, because either end begins with brown. Typically the preci-
sion stripe (which is always last) is wider than the rest, kind of like a period. So
always start from the end with the narrow stripe.
