This calculator will let you calculator the total resistance of a parallel resistor circuit. With multiple resistors of the same value this is all you need to do to know the parallel resistance: Keep in mind that the current through an individual resistor does not change when you add resistors in parallel, because adding resistors in parallel does not affect the voltage across the resistors' terminals. Enter the total voltage supply, Resistance of first load, second load and third load and click calculate. A²). This is the correct value. Twitter Facebook Google+ VK. As a test, if we enter resistances … Resistor calculator (series and parallel) If you need a non-standard resistor value you could probably realize a close match using two resistor. Calculateur de résistances série et parallèle. 3 x 0.01 gives 0.00 ??????? I tried it with the same resistances and got 1.56 Ω, as expected. 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. R / N = [x], Capacitor Charge and Time Constant Calculator, Resistor Color Code Calculator and Chart (4-band, 5-band or 6-band), Technical Article - Resistance in Parallel Networks, Mobile World Congress Kicks Off in Barcelona with 5G at the Forefront, Improved DAC Phase Noise Measurements Enable Ultralow Phase Noise DDS Applications, Basic Amplifier Configurations: the Non-Inverting Amplifier, https://play.google.com/store/apps/details?id=com.weebly.apptrunk.basicelectricalcalculator, https://www.electricaltpoint.com/define-resistance-what-are-the-factors-which-effect-resistance/. Simply input how many resistors you have in parallel and the resistance value of each in the unit of Ohms. If you would like to find out the value of power dissipated in the resistor, try the Ohm's law calculator. Regardless, your tools are easy to use and handy. Twitter Facebook Google+ VK. No matter how large the second resistor is, the total current flowing from the power supply will be at least slightly higher than the current through the single resistor. degree; Customer Voice. 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. This tool was designed to help you quickly calculate equivalent resistance, whether you have two or ten resistors in parallel. Resistance is measured in ohms; 1 ohm is equal to 1 volt of electrical difference per 1 ampere of current (1 volt/1 amp). It'll provide you with the equivalent resistance for resistors connected in parallel or series. Series Resistor. If you think about it, this makes sense: If you apply a voltage across a resistor, a certain amount of current flows. This calculator allows up to 10 different resistor values. Parallel Resistor. Resistance … Automatically the equivalent resistance value will appear. In this case, enter any two of the following values: the voltage across the resistor, the current through the resistor, or its resistance in ohms to find the power dissipation in watts. So a parallel resistor circuit having N resistive networks will have N-different current paths while maintaining a common voltage across itself. $$\frac{1}{R_{EQ}} = \frac{1}{R_{1}} +  \frac{1}{R_{2}} +  \frac{1}{R_{3}} + ... + \frac{1}{R_{N}}$$, When you have only two resistors in parallel: $$R_{EQ} = \frac{R_1\times R_2}{R_1+R_2}$$. Here is the formula for total resistance of resistors of equal value when used in parallel: Resistor R: Inductor L: Frequency f Impedance |Z| Ω; Phase φ . The calculator gives 0.56 Ω as the equivalent resistance of a 5 Ω, 10 Ω, 2 Ω, and 1 Ω resistor in parallel. Experiment with the voltage drop and Ohm's Law calculators, or … Switch to Series and Parallel Capacitor Calculator . Résistance série. And I agree you as well with 1.56. mmikerosss, you must have had a finger fault. Once you have the current, calculate voltage for the individual resistors by multiplying the current by the resistance. This parallel resistance calculator calculates the total resistance value for all the resistors connected in parallel. Parallel resistor calculator is a useful tool to solve two or more than two resistors in parallel. Equivalent Resistance. 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. You can input up to 10 resistors in total. 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. If you use two resistor in series it is quite easy to figure out which values give the best match; on the other hand, using a parallel connection it is not so easy (at least for me) to find a good combination. Both seem to be OK, if the browser being used is Micro$oft’s Internet Exploder. 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. Comment/Request Very useful having the computer make the calculation as I tend to make mathematical errors. Doesn’t seem to work below 1ohm ?

This free resistor calculator converts the ohm value and tolerance based on resistor color codes and determines the resistances of resistors in either parallel or series, as well as the resistance of a conductor. 0.01 / 3 = 0.00333--> Start by introducing the values of the resistors you already know (new fields will appear as needed). R 2 ohm (Ω) Add Resistor. Example: Calculate the total resistance of two resistors 20 ohms and 30 ohms connected in parallel. Are you still seeing 2.26 Ω? Let's look at an example for the second, slightly more complicated, mode: The principle is the same as when determining capacitance in series or induction in parallel - you can use it for these calculations too. 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. The following video explains the basics of resistors in series and parallel, which can promote your understanding towards this article. ① Ohm's Law Calculator. Thank you. If you add another resistor in parallel with the first one, you have essentially opened up a new channel through which more current can flow. This app is used to find out all the combinations of these resistors making a desired resistance. Parallel Resistor Calculator: Enter any two of the following values and press the Calculate button. FAQ. Just add the number of resistors in the first column, and then enter the values of each resistor with selecting the proper unit in Ω, KΩ or MΩ. Adding other resistors in parallel will only decrease the resistance, so its not possible that the equivalent resistance is more than 1. Parallel circuit refers to the closed circuit where the current is split into 3 or more paths & finally recombines to complete the circuit. Impedance of R and L in parallel Calculator . The calculator does not go to 3 spots after the decimal and therefore, shows 0.00 Know the value of the resistor (R) We hope this short explanation and our calculator are useful to you. Then enter the values of Resistor 2, Resistor 3, Resistor 4, and Resistor 5. Equivalent Resistance. Making a precision resistor of an odd value using two preferred values. In contrast, the second mode allows you to set the desired total resistance of the bunch and calculate the one missing resistor value, given the rest. The figure below shows a parallel combination of a single resistor and capacitor between the points A and B. You will get the results of voltage drops in volts.
