Resistor Colour Code Wheel for Resistor Colour Codes

Five Band ResistorColor Code High precision resistors have an extra band which is used to indicate the third significant value of the resistance. The fourth color band signifies tolerance. Carefully poke or make a hole through the center of each wheel using a pin, needle, compass point, knife or any other sharp object you have, being careful not to cut yourself in the process.

However, these sayings are often very crude but never the less effective for remembering the resistor colours. There are three options: 4, 5 or 6 bands. In our example, let's say we have the colors: brown, red violet, black and red.

How to Read Resistor Color Codes

Tolerance of a resistor is normally specified in percentage. The tolerance band has increased space between 3 or 4 bands. We need to download and print out the Resistor Colour Code Wheel template using the download button below. The first two coloured bands are the digit or number bands and the third is known as the multiplier. Hence, instead of directly printing the numbers, we print the color codes or color bands. But remember, if you are still unsure of a resistors value, you can always find its resistance using a multimeter or check out our tutorial.

Resistor Color Code Calculator

What is a color code? Is there a fancy way to memorize the order of colors on the chart? Our color code calculator runs this check automatically for you, and if the result is not a standard value, it will display a small tip. History of the Resistor Resistors are a fundamental component in electrical circuits. However, by measuring using a multimeter or ammeter, we can get the exact measurement of in the resistor. This gap helps in resolving the reading direction. All coded components have at least two value bands and a multiplier; other bands are optional. Similarly, the E48 2% range is a subset of the E96 1% range and the E96 range is a subset of the E192 0.

Resistor Color Code Table

Position the resistor with this band on the right side and again read your resistor from left to right. Select the first 3 or 4 bands for 20%, 10% or 5% resistors and all 5 bands for precision 2% or less , 5-band resistors. The printed colors gives an accurate representation on the value of the resistor. Standard Resistor Values and Color Components and wires are coded with colors to identify their value and function. For blind people, it is impossible to find the resistance of the resistor, because they cannot see the colors coated on the resistor.

And also, the entire body of the resistor is colored; there are one or more colors on the ends of the resistors called as tip colors and lastly, there is a spot of paint on the body. It explains how to use the chart to find the first two digits, the multiplier and the tolerance level which can be used to determine the range in which the true resistance lies in. Similarly, a resistor that has a tolerance of 8% may vary 8% of its resistance from its actual resistance value. Such capacitors were common in equipment and in surplus for a generation after the war but are unavailable now. To avoid this six band resistor is used.

Resistor Color Codes: Calculate Resistor Values From Color Codes

Two wires of each color were provided for each circuit, and phasing was not identified by the color code. Make sure that the hole you make is big enough to both insert and rotate the paper fastener, or whatever you decide to use. Low-tolerance capacitors may begin with the first 3 rather than 2 digits of the value. Note, that the E24 range is technically also a subset of the E48 range, however, because of the different number of digits used for representation and rounding errors, the corresponding values in the two series do not match. They have many uses in circuits, such as for example regulating current flow to or controlling the amount of voltage reaching an active device such as a.

Resistor Color Code Guide

The next to the first band is second band and so on. For 6 band there's additional ring indicating the coefficient - read more about it in a paragraph dedicated to 6 band resistors. Another drawback is recognizing the difference between two colors in an overheated resistor is very difficult. This article has also been viewed 188,294 times. The calculation is similar to three digit code.

Resistor Color Code Chart Tutorial Review

How to remember color codes on the resistor? Resistors come in a range of tolerances but the two most common are the E12 and the E24 series. Again, by matching the colour of the second band with its associated number in the digit column of the colour chart we get the second digit of the resistance value and so on. Audio transformers for vacuum tube equipment were coded blue for the finishing lead of the primary, red for the B+ lead of the primary, brown for a primary center tap, green for the finishing lead of the secondary, black for grid lead of the secondary, and yellow for a tapped secondary. To use this tool, simply click on a particular color and number and watch how the actual bands on the resistor illustration change. The would then be coded as yellow 4 , brown 1 , yellow 4 , grey 8.
