resistor color code formula
Now we can calculate the resistance of the resistor in the picture by using above formulae and from table ie R numbers multiplier tolerance Orange colour 3. Colors of resistors and each color of resistor represents specific number.

The 4 band color code is the most common reliable color coding method to find the resistance value of a lead resistor.
. 5 Band Resistor Color Code. R multiplier x digit1 x 100 digit 2 x 10 digit3 tolerance. Digit Digit Multiplier Colour Colour x 10 colour in Ohms Ω For example a resistor has the following coloured markings.
When was the Resistor Colour Code invented. Measuring power across a Resistor. Formulas are powerful tools.
These body colors are white and blue and sometimes composite green depending on where you live and are used to. Yellow Violet Red 4 7 2 4 7 x 102 4700Ω or 4k7 Ohm. Violet and green indicate the significant.

Resistor Color Code and Types of Resistors Introduction to Resistors. Lets us look into a example.
Formula chart to decode the resistance value by color code. 1st Color Band First Number of Value of Resistor. The 5 band resistor color code has 3 digits 1 multiplier and 1 tolerance at the end.
Red colour 2. In this picture we can see a resistor of 1-orange colour 2-red colour 3-brown colour 4- gold colour. Brown colour 101 and.
4 Band Resistor Color Code Calculator. V is the voltage across the resistor in Volts I is in current flowing through the resistor in Amperes R is the resistance of the Resistor in Ohms Ω By using above two formulas we can transform into many forms as. In this the gold is of 5 and the silver.
I forgot to mention a very important thing there are two resistor body colors which you should know what they are if you are thinking of repairing electronic circuits. 2nd Color Band Second Number of value of Resistor. Below mentioned are the number and the color of resistors.
Find the value of carbon resistor with colour bands Yellow Violet Brown Gold. It has 6 colors. The first two colours in the four-band resistor viz.
0 black 1 brown 2 red 3 orange 4 yellow 5 green 6 blue 7 violet 8 grey 9 white. 33rd Color Band The number of Zeros as multiplier with the first two digits of. Resistivity 47 X 10 1 - 5 Ω.
Depending on the resistor color code 4 or more rings are printed on the resistor. 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. This article provides you the Resistor Color Code chart to calculate the equivalent resistance also shows the Resistor Color Code Animation.
The formula to find the resistance of 5 band system is. The resistor colour code was developed in the 1920s by the Radio Manufacturers Association RMA. All that information is derived from that one little formula.
In short If there are three color bands marked on a resistor it means. Brown 10 1. These are rounded to 22 and 47 thus defining the E3 series.
Because the number of rings in the resistor color code is limited and resistors usually do not have to be dimensioned so exactly the resistor values are rounded to two or three digits. We can find power using. PV 2 R PI 2 R.
This tool is used to decode information for color banded axial lead resistors. The A B C Tolerance are the 4 color bands which represents the actual value of a resistor. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.
