THE RESISTOR
Rather than having their resistor values printed
on them in numbers, these tiny components use
colored rings. That means that they are easy to
read regardless of their orientation.
Depending on their position, the individual rings
designate the first or second digit of the number
value along with the number of zeros that follow.
The table below shows which ring stands for
which digit or for the following zeros, and what
each color means in terms of numbers.
