حساب قيمة المقاومة بالألوان

Can see the value of electrical resistance in two ways either by measurement device Digtl Mmeltmitr and either by code colorimetric and methods are complementary to each other. When we measured the resistance value by measuring device will we get to a certain value, but how to make sure that this is a real value and represents the value of the resistance has also been made to make sure that the value obtained is the real value of the resistance we use a method called method code color is a way we can know the value of resistance before the measured and after measurement we match obtained from the measurement value with the obtained value by the code colorimetric If the two values ​​are equal or that one of them greater or less than the other in the allowable error rate in the border resistance are intact and can be used either if the difference between the great values ​​and outside the borders of the error rate, this resistance is considered stale and should be changed
