#RESISTOR COLOR CODE CHART CODE#
Once you know to calculate resistance using colour Code of resistors, it will be easy for you to design and using resistors in the electronics circuit. for manimum resistance value, 21kΩ or 21000Ω – 5% = 19,950Ωįinally, we get the final value of resistance is in the range of 22,050 to 19,950 Ω.
Another way to set the color chart to memory is to think of black as the absence of color, so it is 0, while white is the combination of all colors, so it is the highest value, 9.
The 5% tolerance resistor may have a maximum and minimum value of resistance. Unique Resistor Colour Chart Posters designed and sold by artists. Last is the Gold band having tolerance value in 5% (0.05) from the table. 21įrom the table, the third orange band has value 1000. The first two digits of the band show the value of resistance 2 and 1 i.e. The Red band of the resistance value is 2 and the brown band of the resistance value is 1 from the table. So the final formula you can use to calculate resistance: Resistance = ((10x + y) z) (p/100) (Unit- Ohm)Ĭonsider, a resistor is having four different colour bands red, brown, orange, and gold respectively as shown in the below diagram.įirstly choose the value of colour from the table. (Says z)īand D: The fourth band (D) or last band shows the tolerance in percentage (%). (Says y)īand C: Third colour band (C) is the decimal multiplier and gives the number of zero after two digits. (Says x)īand B: The second colour band (B) represents the second digit of the numerical value of resistance. Here, each band position and its colour has specific significance to calculate resistance value.īand A: A first colour band (A) represents the first digit of the numerical value of the resistance. BB ROY of Great Britain had a Very Good Wife. Then the resistance of using the color wheel is: Since this is a 4-band resistor, the resistance color code wheel can be used to find the resistance value of a 5-band resistor, so the third digital wheel is not used in this case.
You can use this simple phrase to remember the sequence color band and its values. The color bands are displayed as: YELLOW, VIOLET, ORANGE and GOLD. Note: I know, it is not easy to remember the value corresponding to each color band.
