Code Couleur Resistance Pdf. In some cases this might even be the only way to figure out the resistance; Resistor colour coding uses colored bands to easily identify a resistor resistive value and its percentage tolerance.the resistor color code markings are always read one band at a time starting from the left to the right, with the larger width tolerance band oriented to the right side indicating its tolerance.
4 band resistor color code calculator. Resistance resistor color code band 1 band 2 band 3.22 ohm r22 red red silver.27 ohm r27 red purple silver.33 ohm r33 orange orange silver.39 ohm r39 orange white silver.47 ohm r47 yellow purple silver notation tolerance.56 ohm r56 green blue silver.68 ohm r68 blue gray silver.82 ohm r82 gray red silver 1.0 ohm 1r0 brown black gold To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change.
With This Information, The Resistance Is Determined By Taking The First Two Digits, 1 And 0 (10) And Multiplying By 1,000.
The below equation shows the method to find the resistance: 16 rtd ot 31 tc signals. For example when the color bands are burnt off.
Consider, A Resistor Is Having Four Different Colour Bands Red, Brown, Orange, And Gold Respectively As Shown In The Below Diagram.
Resistors and circuits module 02 pdf 5 e. What is resistor colour code? So the final formula you can use to calculate resistance:
R = 249 X 1000 R = 249, 000 Based On These Figures, We Can Compute The Resistance Of Our Final Sample Smd Resistors To Be 249, 000 Ohms.
4 band resistor color code calculator. Theory there are two ways to find the resistance value of a resistor. Html color code chart rgb number color codes color use hex codes red green blue 1 red (fast) #ff0000 255 0 0 2 dark red (ok red) #8b0000 139 0 0 3 maroon no humans #800000 128 0 0 4 tomato (vitalizing) #ff6347 255 99 71 5 violet red (crazy depression) #d02090 208 32 144
Different Codes Are Used For Wire Leads On Devices Such As Transformers Or In Building Wiring.
We can calculate the actual resistance of the smd resistor by multiplying our base resistance of 249 by our multiplier of 1000. Of the resistance.a resistor calculator is a tool that helps in decoding information for the color band axial lead resistors. The chart demonstrates the values of each color band and how to read them.
This Tool Is Used To Decode Information For Color Banded Axial Lead Resistors.
The resistance value based on the color code provided is now displayed. The resistor colour code was invented in the 1920s by the radio manufacturers association (rma). The resistance value is a discrete value.
