Tolerance band on the right hand end of the colors refer to the tolerance chart below for exact values. Decoding the nominal value of a resistor.

How To Read Color Codes From Resistors Instructables

If the 3rd band would be red instead of brown the multiplier would be 10 2 100 instead of 10 and the resistor value would be 56 x 100 5600 ohms 56 k ohms.

How to red resistor. Decide which band is the first band. Or there are much resistor calculators that you can use. This tool is used to decode information for color banded axial lead resistors.

If you have a resistor with a gold or silver band on one end you have a 5 or 10 tolerance resistor. Position the resistor with this band on the right side and again read your resistor from left to right. As you can see they are.

If there is no tolerance band then find the side that has a band closest to a lead and make that the first band. Hold the resistor or diode with the stripes to the left. However its your decision and i will show you all ways to calculate resistor value.

The brown band 1 the red band 2 the orange band 3 and the gold band means that the value of the resistor is within 5 of the number shown by the other bands. How to read the code. Colors here is the table with the colors and numbers.

Learn more about resistors and resistor color codes. As can be seen in the above 4 band resistor color codes chart the first two color bands have values of brown 1 red 2 orange 3 and so on. The resistor value is read from the left to right.

Here black is 1 brown is 10 red is 100 and so on. Compare the ends of the resistor. The first band is the first digit and the second band is the second digit so you get 12.

Its for the laziest people d. Putting this in other words the value of the third band the multiplier is the number 10 raised to the power of the color code. Heres how you use the color code to figure out the nominal value of the resistor refer to the figure.

The power flows from the end without the stripe to the end with the stripe. 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. If the multiplier band is gold or silver then the decimal point is moved to the left one or two places divided by 10 or 100.

Basic resistor values range from 01 ohm to 10 megaohms. Look at the first color band and determine its color. Usually the colored band at one end is closer to that end than is the colored band at the other end.

To determine the value of a given resistor look for the gold or silver tolerance band and rotate the resistor as in the photo on the left. The third color band is the multiplier of the first 2 bands. Look for the marking a colored stripe on the diode or resistor that indicates which way the current flows.
