resistor color code formula
The formula for the three-band resistor color code is 1st digit. Calculating resistance for a 5-band resistor.
Resistor Color Code Coding Resistor Color Coding
Hence the colour red represents a multiplier factor of 10 2.
. As we know the first two colours represent the significant digits of resistance value so the given colours represent digits 2 and 5. 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. By the way the phrase is translated as Four cows paint a rusty iron fence with synthetic formula containing protein.
Example - Value Five Band Fixed Resistor. 4 Band Resistor Color Code Calculator. Note that resistor R4 has the value 47 Ω and resistor R12 has the value 330 Ω.
Body End Stripe Body 1 st digit End 2 nd digit Stripe Multiplier. So according to the formula the resistance will be. There are two major types of resistors.
Just have a look to the resistor color code chart below and see the calculations how the resistance value is calculated according to this chart. The multiplier band goes. Yellow Violet Red 4 7 2 4 7 x 102 4700 or 4k7ohm.
The resistance value is displayed on the field below together with the. Figure 10 Dot and stripe code Resistor colour code. So for the E3 row x 3 for the E12 row x 12 and so on.
Step 1 Address the formula input parameters AB x 10 c Tolerance Band A Green 5 Band B Violet 7 Band C Blue 6 Tolerance Silver 10 step 2 Apply the corresponding values in the resistance color coding formula Resistance 57 x 10 6 10 57000000 10 57 Mega ohm 10 Step 3 Find the Tolerance. For the E3 series r is 2154. The colour codes are as follows.
6 Band Resistor Color Code Calculator. If you are interested in learning the code by memory try the steps below to help you Learn the Color-code. This results in the resistance values for the resistors between the powers of ten.
Three first bands first band is the one nearest the end of the resistor indicates the value the fourth indicates the multiplier and the fifth indicates tolerance. The old mnemonic was rather well disturbing and a conscientious person would never recite it. Third digit x Multiplier 103 X100 103-kilo ohm 5 100 ppm o c.
In circuit diagrams and constructional charts a resistors numerical identity or designator is usually prefixed by R. This resistor read from left to right has the colored bands of RED VIOLET YELLOW SILVER. Thus this is all about an overview of resistor color code for 3 bands 4 bands 5 bands and 6 bands.
R RED X. Consider a resistor is having four different colour bands red brown orange and gold respectively as shown in the below diagram. Black0 brown1 red2 etc etc.
13 rows The formula for the three-band resistor color code is 1st digit. Make sure you add the number to the color like. Again just the color code associated with a number like.
R 1st Digit x 10 2nd Digit x Multiplier. This tool is used to decode information for color banded axial lead resistors. There is no particular formulae but the resistance using the color codes is like Rnumbersxxmultiplier-tolerance.
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. A resistor with the five color bands. For 4-band and 5-band resistors the last band indicates the resistor tolerance.
Their values are given using a colour code. It means we will take the values of the first two or three bands from the left depending on the total number of bands then we will multiply that value by the multiplier to get. Now lets discuss the resistor colour coding formula.
Resistor Colour Coding Formula For calculating the resistance colour code calculator we need to group the values of the significant digits bands. 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. Five Band Fixed Resistor.
Since it is a four-band resistor the first two bands violet and green will indicate the significant digits which are according to the table above. A wire bound resistors b carbon resistors. Formula of factor r in a e-series.
The third band is a multiplier band. Download and print Resistors - Standard Colors Codes table. Using the formula and chart above the resistance would be.
Resistor color codes are something that every electronics hobbyist should remember. Q1 Determine the resistance of the given resistor with the given colour sequence Red Green Red Gold. Body End Dot Body 1 st digit End 2 nd digit Dot Multiplier.
When looking at the chart note the illustration of three round resistors with numerous color code bands. Resistance 1st Digit x 10 2nd Digit x Multiplier. We then multiply that number by the multiplier indicated with the 3 rd band yellow which has the value of.
The next a 5-band code provides a. Resistor Colour Code Examples. We shall use the colour.
Resistance 10x y z p100 Unit- Ohm Example of Resistor Colour Code. For example R15 simply means resistor number 15. Use the Resistor Color Code Chart below to understand how to use the color code system.
The resistor value is read from the left to right. 152 1 152 Ohms with 5 tolerance. A portion of a schematic diagram showing designators and IEC labelling is shown below.
5 Band Resistor Color Code Calculator. To use this tool simply click on a particular color and number and watch how the actual bands on the resistor illustration change. The first resistor in the chart with 4 bands tells you the minimum information you can learn from a resistor.
The factor r is calculated from the x-th root of 10 where x is the number of resistors in a decade. Carbon resistors are compact and inexpensive. So the final formula you can use to calculate resistance.
0 is black 1 is brown 2 is red etc.
