223 shall be written as 2 2 X 10^3 i.e.220 shall be written as 2 2 X 10^0 i.e.403 shall be written as 4 0 X 10^3 i.e.102 shall be written as 1 0 X 10^2 i.e.Here the first two digits should be written as it is and replace third digit is the multiplier with 10 to the power third digit (10^3rd digit) and that is the value of preset in Ohms. But smaller presets will have their values mentioned in code format also. The third band of the 4. The 4.7k&ohm resistor shown here has color bands of yellow and violet to begin - which have digit values of 4 and 7 (47). That is why the colored rings are made on resistors and standard color code is followed across globe.īigger variable resistors or presets will have their value directly printed like 10K, 100K, 4K7 (4.7K) and 3K3 (3.3K) etc. For the first two bands, find that colors corresponding digit value. The value of variable resistors or presets are mentioned on their body as they have sufficient space as opposite to simple resistor which have small cylindrical body and limited space to print their value. Description and SKUPrice 110101001001KResistor 18 Ohms.25W/5 EIDR025018.12.09.05Resistor 24.9 Ohms.25W/1 EIDR02524X911.20.49.25Resistor 49.9 Ohms.25W/1 EIDR02549X911.20.49. In order, the colors are: black, brown, red, orange, yellow, green, blue,violet, gray, and white.This is the symbol of a preset. Resistors have standard colors foridentification of the resistance value. Resistor Color Code Chart and ResistanceCalculator. Keeping this in consideration, what is the resistor code color for a resistance of 6? These coloured painted bands produce a systemof identification generally known as a Resistors ColourCode.Īlso Know, what is the color code for a 100 ohm resistor? 100R / 100 ohm Resistor Colour Code Value So to overcome this, small resistors use colouredpainted bands to indicate both their resistive value and theirtolerance with the physical size of the resistor indicatingits wattage rating. All 5-band resistors use a colored toleranceband.Ĭonsequently, why are resistors color coded? The colors brown, red, green, blue, and violet are used astolerance codes on 5-band resistors only. Standard Resistor Values and Color Components and wires are coded with colors to identify their value and function.
