![]() ![]() The last bands in 4 or 5-bands resistors are the indicator of the tolerance value of the resistor.Next 3rd digit ‘0’ (but value 10^1 = 10) is multiplier ‘ 1 ‘, ∴ look for color in a chart with value 1, then it’s your 3rd color band (say brown). The next 2nd digit is ‘ 7 ‘, ∴ look for color in a chart with value 7, then it’s your 2nd color (say violet). So for 470-ohm resistor, 1st digit is ‘ 4 ‘, ∴ look for color in a chart with value 4, then it’s your 1st color(say yellow). ∴ the real value of 470 Ω resistor is between 446.5 Ω to 493.5 Ωĭescription: From the resistor code chart we found the color code of resistor with respect to the decimal value of the respective band counted from left to right. ![]() ![]() 470 ohm resistor color code for 4-band is calculated as: ![]()
