Our Resistor Color Code Calculator is a handy tool for reading carbon-composition resistors whether its a 4-band 5-band or 6-band type. 2 nd Digit. Hence the colour code of 220 ohm resistor will be red red and brown.
Its also easy to classify them by decade. Red is Ks orange is 10Ks. 1k0 1k ohm Resistor Colour Code.
Your units are ohms for resistance volts for voltage and amps for current. 5 Band Resistor Color Code Calculator. Digit Digit Multiplier Colour Colour x 10 colour in Ohms Ω For example a resistor has the following coloured markings.
Resistors have standard colors for identification of the resistance value. 4 Band Colour Code. So according to the formula the resistance will be.
Where V is voltage I is current and R is resistance. 1 st Digit. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.
The resistor value is read from the left to right. Code Brown Black Red Gold. This formula tells you that your resistance is always equal to your voltage divided by the current.
Lets take an example of a 5-band resistor with the colors given in the above image brown green red black and gold. In military equipments extra color band Reliability band on resistors specifies failure rate in per 1000 Hrs of service. 4- Band Code 5- Band Code RESISTOR COLOR CODE GUIDE 2 0 x10000 10 20 x 10000 200000 1000 1K Resistor 200 K with a 10 Tolerance-First Band Second Band Multiplier Band Tolerance Band Equation The Gold or Silver band is always placed to the right.
Because carbon resistors are physically small they are color-coded to identify their resistance value in ohms. 14 rows Since it is a four-band resistor the first two bands violet and green will indicate the. Typical resistors will display the following coloured markings.
3 rd Digit x Multiplier. Gold Band 5. The following formula can be used to know the value of resistance of a six band resistor.
To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change. There are four and five bands used to determine the resistors resistor percentage tolerance. 13 rows The formula for the three-band resistor color code is 1st digit.
To read the whole thing put the tolerance band at your right and go like this. In addition to determining the value of resistance the color code of the resistor on the 6th band of the color band is also used to determine the temperature coefficient of a resistance. 4 Band Colour Code System.
So the final formula you can use to calculate resistance. The resistance value is displayed on the field below together with the. You must select the right color corresponding to each column.
How to Find the Value of resistance of a Five Band Resistor Color Code. The other formula you need with resistance is Power P. What is the color code for a 220 ohms 5 resistor.
The relationship between conductivity and resistivity is. Tolerance in Temp Coefficient. In Figure 3 above is a chart of resistor color codes from 4 bands to 6 color bands.
Resistance 10x y z p100 Unit- Ohm Example of Resistor Colour Code. Green-brown-red-gold 5-1-00-5 51K 5. 47k 47k ohm Resistor Colour Code.
The easiest way to transpose any formula is what I call the Transposition Triangle which can and will be applied to other formulae. The tolerance value tells the accuracy at which the resistor is manufactured. Select the number of bands then their colors to determine the value and tolerance of the resistors or view all resistors Digi-Key has to offer.
Third digit x. What color is a 47k resistor. How Do You Calculate Resistor Color Code.
1 kΩ 1000 Ω. Black brown red orange yellow green blue violet gray and white. The use of color bands on the body of a resistor is the most common system for.
The resistance calculator has 1 to 6 band colors with Multiplier Mul and tolerance Tol and PPMKelvin. This tool is used to decode information for color banded axial lead resistors. What color is a 1k resistor.
