So according to the formula the resistance will be: 152 * 1 = 152 Ohms with 5% tolerance. 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. ‘ d’ represents the 4 th significant digit, which is the fourth band color of resistor and this is the multiplier value used in formula. ‘ c’ represents the 3 rd significant digit, which is the third band color of resistor. Here is the color coding chart to determine the resistor values Resistors with four bands are > 1 tolerance. ‘ b’ represents the 2 nd significant digit, which is the second band color of resistor. 1 K Ohm colors are - Brown - black - red. ‘ 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
To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.
A resistor is identified by its pattern of color of bands.
