Online programing or coding or mobile app or website development course. The value of the resistance is marked with the colors. Color inspiration or colour chart with codes template. From the resistor color code chart, the first two bands corresponds to the digits of the value, 3 3. The bands on this resistor are Orange Orange Brown Gold. OK, let's get down to brass tacks: How to read resistor color code? The color bands indicate the resistor value and tolerance. If none of the above appear to help your problem, you can always use a multimeter to tell between two possible resistances – and reading directions. Usually, the first band will be closest to the end (but not always, so then use other clues). Again, read the resistor from left to right. However, the resistor color code never starts from such color – so if you find the metallic color on your resistor, it's definitely the tolerance value, so it must be placed on the right side. Enter 1st Digit In the 1st Digit option, input the value of the first digit of your resistor’s color code. Options include 3 bands, 4 bands, 5 bands, or 6 bands. , 4 Band Resistor Color Code Calculator., 5 Ways to Calculate Total. Select Band Count In the Band Count option, choose the appropriate number of bands for your resistor. These values are marked with metallic colors – gold and silver, respectively. Online System (CROS), to facilitate electronic filings and transactions. This voltage divider calculator employs the following formulas: V out V. Very often, the tolerance of the resistor is equal to 5% or 10%. Resistor Color Code Band 1 Band 2 Band 3.22 ohm R22 Red Red Silver.27 ohm R27 Red Purple Silver.33 ohm R33 Orange Orange Silver.39 ohm R39 Orange White Silver.47 ohm R47 Yellow Purple Silver Notation Tolerance.56 ohm R56 Green Blue Silver.68 ohm R68 Blue Gray Silver.82 ohm R82 Gray Red Silver 1.0 ohm 1R0 Brown Black Gold 1. Lets say we would like to determine the output voltage if the resistance of resistor R1 is 5K, the resistance of resistor R2 is 10K, and the input voltage is 9V. Put the bigger group on the left side and read resistors from left to right. The flow of electric charges in a metallic conductor, Carbon resistors, color code for carbon resistors, Potentiometer-principle and. The larger gap occurs before the tolerance band. In a usual case, the bands are not spaced regularly – there's a gap, and bands are somehow grouped. This calculator supports resistors with 3, 4, 5, and 6 bands. It will also calculate the minimum and maximum values based on the tolerance ratio. Generator 110 Global Positioning System (GPS) 13, 47 Receiver 47. This calculator will help you identify the value, tolerance and temperature coefficient of a color coded resistor by simply selecting the bands colors. ![]() The first question which usually arises is: how do I know from which end I should start reading my resistor color code?įortunately, a couple of visual hints exist! Resistor Color coding 82 Fixed 81 Online color code converter 82. The printed alphanumeric codes would be too small to read on the tiniest resistors, so the color code was developed in the early 1920s. Color bands are an easy and cheap way of indicating the value of an electronic component.
