# on video How to Read a Resistor

Resistor Values are read starting from the line closest to the end of the resistor. They will either have 4 bands or 5 bands.

If there are four bands then the first two are the value of the two most significant digits, the third is the multiplier, and the fourth is the precision. If there are five bands then the first three are the value of the three most significant digits, the fourth is the multiplier, and the fifth is the precision. Use the resistor color code chart below to determine how to read a color coded resistor.

r example take the following resistor which has bands Green, Blue, Yellow, and Gold. Since there are four bands the third band is the multiplier and the fourth band is the tolerance. Looking at the chart below:

Green = 5 (tens of places)

Blue = 6 (ones place)

Yellow = 10KÎ©

Gold = 5%

Understanding the value. Put the 5 and 6 together for 56 then multiply by 10KÎ© - 56*10KÎ©=560kÎ©.

Understanding the tolerance. The tolerance is +/-5% - 560kÎ©*5%=28kÎ© which means the resistor may be 28kÎ© lower or higher than the stated value. 560kÎ©-28kÎ©=532kÎ©. 560kÎ© + 28kÎ© = 588kÎ©. So the acceptable resistance of this resistor is between 532KÎ© and 588KÎ©.
