47 k subscribers(i.redd.it)

E3 standard resistor values are 10, 22, 47, 100, 220, 470, 1 k, 2.2 k, 4.7 k, 10 K, 22 k, 47 k, 100 K, etc.

To further clarify why these particular numbers were chosen:

"The E series of preferred numbers were chosen such that when a component is manufactured it will end up in a range of roughly equally spaced values on a logarithmic scale."

And be able to sell each manufactured component by just putting the "correct" colors on it...
