Let’s take an example of a 5-band resistor with the colors given in the above image (brown, green, red, black and gold). ‘ e’ represents the 5 th significant digit, which is the fifth band color of resistor and this is the tolerance value of resistor.
#220 resistor color code code
‘ d’ represents the 4 th significant digit, which is the fourth band color of resistor and this is the multiplier value used in formula. Resistor color code calculator (above) gives you the opportunity to learn resistor value and its tolerance regardless of how many color bands is contained in. ‘ c’ represents the 3 rd significant digit, which is the third band color of resistor. ‘ b’ represents the 2 nd significant digit, which is the second band color of resistor. ‘ a’ represents the 1 st significant digit, which is the first band color of resistor. Just have a look to the resistor color code chart below and see the calculations, how the resistance value is calculated according to this chart.Ĭalculating resistance for a 5-band resistor A resistor color code refers to using colored bands to spot chip resistors percentage tolerance and resistive value.
To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator. Supports resistors with 3, 4, 5 and 6 bands. Resistor 220 Ohm 5 1/4W (25-Pack) quantity. A resistor is identified by its pattern of color of bands. The Resistor Color Code Calculator identifies the value and tolerance of a color coded resistor given its bands colors. Strong leads and easy to read color coding for breadboarding.
