This app is used to find out all the combinations of these resistors making a desired resistance. $$\frac{1}{R_{EQ}} = \frac{1}{R_{1}} +  \frac{1}{R_{2}} +  \frac{1}{R_{3}} + ... + \frac{1}{R_{N}}$$, When you have only two resistors in parallel: $$R_{EQ} = \frac{R_1\times R_2}{R_1+R_2}$$. Close. We hope this short explanation and our calculator are useful to you. Input. To calculate the total impedance (resistance) of this circuit we again use the capacitative reactance Xc as the equivalent resistance of the capacitor. 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. 0.01 (resistor value) / 3 (number of resistors) = [parallel resistance value] R 2 ohm (Ω) Add Resistor. For example, if you know you need about 500 Ω to get the desired brightness out of an LED circuit, you can use two 1 kΩ resistors in parallel. Impedance of R and L in parallel Calculator . A²).

Our parallel resistor calculator eliminates mistakes in transcription and helps you verify your answers. Then enter the values of Resistor 2, Resistor 3, Resistor 4, and Resistor 5. 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. And if the total current is higher, the overall resistance must be lower. Parallel resistance calculator to calculate the values of resistors in parallel in a circuit COVID-19 update We are trading as normal but our posting days have changed. And I agree you as well with 1.56. mmikerosss, you must have had a finger fault. 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. The following video explains the basics of resistors in series and parallel, which can promote your understanding towards this article. Then, divide the voltage across the circuit by the total resistance to find the current. Ask An Engineer! Automatically the equivalent resistance value will appear. 13.
