How To Measure Resistance Of A Resistor Using Color Code

- September 14, 2019

The power rating of the resistor depends upon the physical size of the resistor. First and foremost we must know what is resistor color code.

Lab 1 Basic Resistive Circuit Calculation And Measurement

Iec Labelling For Resistors Color Code Instrumentation Tools

How Would You Compare And Contrast Colour Code Values And

The color coding of these color bands on the resistor is used to identify the value and tolerance.

How to measure resistance of a resistor using color code. It is sometimes easier to remember the resistor colour code by using mnemonics or phrases that have a separate word in the phrase to represent each of the ten two colours in the code. This physics video tutorial explains how to use the resistor color code chart to determine the value of the resistance of a resistor in an electric circuit. Hence color bands are printed to calculate the resistor value using color code on resistors.

To learn to use the ohmmeter to measure resistance and continuity. To compare the color coded resistor tolerance with the actual measured resistance value. As the carbon film and carbon composition resistors are very small in size to print the value of resistance.

It explains how to use the chart to. Resistance measurements and resistor color codes lab. If resistor has no fourth tolerance band then the default tolerance would be at 20.

To identify resistor values and tolerances from the color code and measurement. When comes to measure the value of resistor we can do that by several ways. One way is to use multimeter.

Resistance values determined using resistor color code. There are four different color bands a b c and d printed on the resistor body as shown in below figure. How to calculate resistance using color code.

But one can also read value of resistor by using color code menthod in case of through hole type or simply by having reference of number marking in case of surface mount type. Brown 1 red 2 gold 5 silver 10.
