Why is a color code used for resistors?

There are many different types of Resistors available which can be used in both electrical and electronic circuits to control the flow of current or to produce a voltage drop in many different ways. But to do this, the actual resistor needs to have some form of “resistive” or “resistance” value. Resistors are available in a range of different resistance values from fractions of an Ohm ( Ω ) to millions of Ohms. Obviously, it...
