Then, divide the voltage across the circuit by the total resistance to find the current. This calculator will let you calculator the total resistance of a parallel resistor circuit. And I agree you as well with 1.56. mmikerosss, you must have had a finger fault. For example, if you want to compute the parallel resistance of 3 resistors, just insert values into the first 3 boxes and leave … Create one now. Resistors in parallel, on the other hand, result in an equivalent resistance that is always lower than every individual resistor. Home / Science / Electricity and magnetism; Calculates the impedance of the resistor and inductor in parallel. This tool calculates the overall resistance value for multiple resistances connected either in series or in parallel. Know the value of the resistor (R) Please try to fix the algorithm, otherwise great tool! Start by introducing the values of the resistors you already know (new fields will appear as needed). R 2 ohm (Ω) Add Resistor. As a test, if we enter resistances … Features: 1. 0.01 (resistor value) / 3 (number of resistors) = [parallel resistance value] You can easily calculate the equivalent resistance when you have two identical resistors in parallel: it is half of the individual resistance. Input. Ask An Engineer! We hope this short explanation and our calculator are useful to you. Parallel and Series Resistor Calculator; Reactance Calculator; See All Calculators × Need Help? The calculator does not go to 3 spots after the decimal and therefore, shows 0.00 0.01 / 3 = 0.00333--> 0.01 (resistor value) / 3 (number of resistors) = [parallel resistance value] With multiple resistors of the same value this is all you need to do to know the parallel resistance: Know the value of the resistor (R) Know how many resistors you are using (N) read the output (x) Here is the formula for total resistance of resistors of equal value when used in parallel: … This is the minimum power rating you can use on your resistor. Great tool, but there seems to be an error! Resistor R: Inductor L: Frequency f Impedance |Z| Ω; Phase φ . So there, it's settled. R 1. Enter the total voltage supply, Resistance of first load, second load and third load and click calculate. Making a precision resistor of an odd value using two preferred values. 0.01 / 3 = 0.00333--> It is used to calculate equivalent resistance of the parallel resistor. The equivalent resistance of a 4-Ω and 12-Ω resistor placed in parallel can be determined using the usual formula for equivalent resistance of parallel branches: 1 / Req = 1 / R1 + 1 / R2 + 1 / R3. Now input the total resistance you want you circuit/collection of resistors to have. Our parallel resistor calculator eliminates mistakes in transcription and helps you verify your answers. LED Parallel Resistor Calculator Parallel resistors are connected together in parallel when both of their terminal is connected to each terminal of the other resistors. Résistance série. The first mode allows you to calculate the total resistance equivalent to a group of individual resistors in parallel. The calculator gives 0.56 Ω as the equivalent resistance of a 5 Ω, 10 Ω, 2 Ω, and 1 Ω resistor in parallel. Oh, the joy of making javascript work across multiple browsers! A²). Enter resistances into the boxes below and when all values have been input, click on the 'calculate' button and the result will appear in the box below that button. Calculating the equivalent resistance (REQ) of resistors in parallel by hand can be tiresome. After entering all of the required values, the parallel circuit calculator automatically generates the result you need. This tool was designed to help you quickly calculate equivalent resistance, whether you have two or ten resistors in parallel. Resistors in series are equivalent to one resistor whose resistance is the sum of each individual resistor. Digi-Key's team of Engineers and Technicians are ready to answer your questions on the TechForum. Share a link to the calculator, including the input values. Enter resistances into the boxes below and when all values have been input, click on the CALCULATE button and the result will appear in the box below that button. Doesn’t seem to work below 1ohm ? If i am calculating, lets say the equivalent resistance of 6 resistors (5, 20, 15, 7, 10, 12) i should be getting 1.56ohms but instead i get 2.26ohms. Impedance of R and L in parallel Calculator . What are Parallel Resistors There are three basic configurations in which we can arrange the electrical components. PARALLEL RESISTOR CALCULATOR This calculator can determine the resistance of up to 10 resistors in parallel. Hello, It would be nice to add a button to confirm the number of resistors in parallel, because if you enter a high value, the page may freeze. Cet outil calcule la valeur de résistance globale pour plusieurs résistances connectées en série ou en parallèle. Twitter Facebook Google+ VK. Just remember that the units are not the same! The first mode allows you to calculate the total resistance equivalent to a group of individual resistors in parallel. read the output (x) Adding other resistors in parallel will only decrease the resistance, so its not possible that the equivalent resistance is more than 1. Parallel Resistor. 3 x 0.01 gives 0.00 ??????? Series Resistor. Automatically the equivalent resistance value will appear. The following video explains the basics of resistors in series and parallel, which can promote your understanding towards this article. Parallel resistor calculator is a useful tool to solve two or more than two resistors in parallel. Resistance … This app is suitable for hobbyist or electronic engineers. Résistance parallèle. Since the unit of measurement for all the resistor values is Ω, the final … Equivalent Resistance. To calculate voltage across a resistor in a series circuit, start by adding together all of the resistance values in the circuit. Resistors in series and parallel - deriving the formula. When you do not have an exact resistor value in building a circuit, you need to combine two resistors either in series or in parallel. Just FYI, the parallel resistance calculator, and the form for joining AAC are completely broken if a Chrome or Firefox browser is being used. Are you still seeing 2.26 Ω?
