# Write about color code resistance bands

These free software can calculate resistor codes after you specify the color of the bands printed on them. Some of the following software also comes with other tools as well and you can also get the resistor colors by the value of the resistance you provide. Though, you can decode resistor codes with the help of the color coding table, but there may be situations in which you have to calculate the resistance of many resistors. Calculating resistor codes one by one using the color table can be quite difficult.

Resistors are color-coded for easy reading. Imagine how many blind technicians there would be otherwise. How to Read the Code 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.

Tolerance band on the right-hand end of the colors -- refer to the tolerance chart below for exact values. Look at the first color band and determine its color. This maybe difficult on small or oddly colored resistors.

Now look at the chart and match the "first and second color band" color to the "digit it represents". Write down this number. Now look at the second color band and match that color to the same chart.

Write this number next to the first digit. The third and final color band is the number you will multiply the result by. Match this third color band with the chart -- this time looking at the row of multiplier numbers. This is the number you will multiply the other two digits by.

Write it next to the other two digits, with a multiplication sign before it. Tolerance Explained Resistors are never the exact value that the color codes indicate.

## What is E representing on Resistor value

Therefore manufacturers place a tolerance color band on the resistor to tell you just how accurate this resistor is made. This the the band farthest on the right-hand end of the bands.

It is simply a measurement of the imperfections. That is the number that the resistor may go either way.

A couple of examples: A 1,Ohm resistor with a gold band maybe any value between to Ohms. A 22,Ohm resistor with a silver band maybe any value between 19, and 24, Ohms. Resistor FAQs Just a few common questions to help you out.

The Gold or Silver band is always set to the right, then you read from left to right. Sometimes there will be no tolerance band -- simply find the side that has a band closest to a lead and make that the first band. How do I make certain what the value of the resistor really is?

Occasionally the colors are jumbled or burnt off. The only way to read it is with a multi-meter across the leads 3 How do I remember this sequence of colors? Remember the color codes with this sentence:Nov 03,  · To do the first calculation select the number of bands from the top option box and from left to right, select the color from the band option boxes.

The result calculation is updated interactively. To do the reverse calculation, enter the resistance value complete with trailing 0’s in the input box that says “resistance”, select the.

will also be introduced to the resistor color code and refresh their graphing skills. Theory Resistors are labeled with color-coded bands that indi-cate resistance and tolerance.

The ﬁrst two color bands Experiment Ohm’s Law 83 QUESTIONS 1. Read the information in the next column. Three and Four Band Resistor Color Codes. The first two or three bands determine the significant digits based on the resistor accuracy. digital multimeters, resistance measurement, and the resistor color code.

When the lab is completed, the student will be able to use a multimeter to measure the value of a resistor and Write down the. Here are 5 free software to decode resistor color kaja-net.com free software can calculate resistor codes after you specify the color of the bands printed on kaja-net.com these software, you can calculate resistance of 4, 5, and 6 band kaja-net.com of the following software also comes with other tools as well and you can also get the resistor colors by the value of the resistance you provide.

Sample Readings from Lab Color Bands Resistance From Color Acceptable Range Actual Digital Meter Code (Tolerance) Measurement Brown, Red, Brown, Ohms 5% Ohms Ohms Gold Conclusions One thing I have noticed with the color coding of resistors is if you know anything about the color wheel or the color spectrum, it is easy to grasp.

Our Resistor Color Code Calculator is a handy tool for reading carbon-composition resistors whether it's a 4-band, 5-band or 6-band type. To use this tool, simply click on a particular color and number and watch how the actual bands .
