A resistor is identified by its pattern of color of bands. There are 4, 5 and 6 band resistors. To calculate the resistance of a resistor, you can select the appropriate color bands in the above resistor color code calculator.

### How to calculate the resistance?

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. ### Calculating resistance for a 5-band resistor  Where,

a’ represents the 1st significant digit, which is the first band color of resistor.

b’ represents the 2nd significant digit, which is the second band color of resistor.

c’ represents the 3rd significant digit, which is the third band color of resistor.

d’ represents the 4th significant digit, which is the fourth band color of resistor and this is the multiplier value used in formula.

e’ represents the 5th significant digit, which is the fifth band color of resistor and this is the tolerance value of resistor.

Let’s take an example of a 5-band resistor with the colors given in the above image (brown, green, red, black and gold).

So according to the formula the resistance will be: 152 * 1 = 152 Ohms with 5% tolerance.
