Resistance Color Code: an easy way to find
There are plenty of resistances available that can be used in both electrical and electronic circuits to control the flow of current flow or to generate the voltage drop in many different ways. But to do so, the actual resistant should have some form of “resistant” or “resistance” value. Resistant ohms (Ω) are available in a series of different resistance values from the parts of the ohm-ohm.
We are providing the easiest way to calculate the value of resistance by its color…
In reality, for example, it will be impractical to find resistance of every possible value, for example, 1Ω, 2Ω, 3Ω, 6Ω etc., because literally thousands of thousands, if millions of different resistors to cover tens Potential value should not exist for Instead, resistors are said to be “preferred values” with resistance printed on their body in colored inks.
Resistant Color Code
4 colored bands
Resistor value, its tolerance, and wattage ratings are mainly printed in numbers or letters on the body of the resistant when the resistance body is large enough to read the print, such as large electrical resistance. But when resistant 1 / 4 W is small in the form of carbon or film type, then these specifications should be shown in any other way because the print will be too small to read.
An international and universally acceptable resistant color code scheme was developed several years ago as a simple and quick way of identifying a resistant ohmic value; it does not matter what its size or position is. In this, there is a set of individual colored rings or bands in the spectral order representing each point of the resistant value.
it starts from left to right, where the larger width is the tolerance band is shifted to the right, indicating its tolerance. In the first column of the band’s chart, the first digit is identified by matching the colors of the first band with its corresponding number and represents the first digit of the resistance value.
Then, by matching the colors of the color of the chart to the number of the color of the chart with our respective number, we get the second point of resistance price and so on. Then the inhibitor color code is read from left to right, shown below:
Now to understand properly look at the table:

A. The first significant figure of component value (left side)
B. The second significant figure (some precision resistors have a third significant figure, and thus five bands).
C. The decimal multiplier (number of trailing zeroes)
D.If present indicates the tolerance of value in percent (no band means 20%)
