The Resistor Color Expert exercise says,
- orange-orange-orange-black-green would be 330 ohms with a ±0.5% tolerance.
There are also one band resistors. This type of resistor only has the color black and has a value of 0.
- Is the “one band resistors” note supposed to be part of the “orange-orange-orange-black-green” example?
- This “only has the color black” implies when there is exactly one color, you can ignore the color and just return
"0 ohms". Is that correct/intentional?
