Next 2nd digit is ‘ 0 ‘, ∴ look for color in chart having value 0, then it is 2nd band color- black. The 1st digit is ‘ 1 ‘, ∴ look for color in table having value 1, then it’s your 1st color- brown. So for 1-ohm 5-band resistor which comes under precision resistor, The 100R 5-band resistor color code is b rown, black, black, silver, black and it is found as: Image showing 1 ohm resistor color code of 5-band resistor: If the 4th band is absent it should be considered as 20% tolerance. For Silver, it is 10%, Black indicates 1% and 2% tolerance is indicated by Brown. In this case, it is Gold which indicates a 5% tolerance value. The last band in 4 and 5-bands resistors is the markings for tolerance value in the resistor.Next 3rd one is multiplier 0.1 ∴ look for color in chart having value 0.1, then it’s your 3rd color will be gold. The next 2nd digit is ‘ 0 ‘, ∴ look for color in chart having value 0, then it’s your 2nd color will be black. So for 1-ohm resistor, 1st digit is ‘ 1 ‘, ∴ look for colour in chart having value 1, then it’s 1st color will be brown. Theoretically, the value of 1 Ω resistor is between 0.95 Ω to 1.05 Ωĭescription: From the chart we got the color code of resistor with respect to the decimal value of the respective band counted from left to right. The tolerance will be –> 5% of 1 –>0.05 Ω 4-band 100 ohm resistor color code is calculated as:
