The figure below shows a parallel combination of a single resistor and capacitor between the points A and B. Know the value of the resistor (R) Home / Science / Electricity and magnetism; Calculates the impedance of the resistor and inductor in parallel. With multiple resistors of the same value this is all you need to do to know the parallel resistance: Enter the total voltage supply, Resistance of first load, second load and third load and click calculate. You can input up to 10 resistors in total. Automatically the equivalent resistance value will appear. There are also some worked examples below the tool. If you want to compute the total resistance of less than 10 resistors, just insert the values of the resistors you have and leave the rest of tbe fields blank. To calculate voltage across a resistor in a series circuit, start by adding together all of the resistance values in the circuit. R 1. 3 x 0.01 gives 0.00 ??????? Input. This parallel resistance calculator calculates the total resistance value for all the resistors connected in parallel. R 2 ohm (Ω) Add Resistor. Switch to Series and Parallel Capacitor Calculator . 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. PARALLEL RESISTOR CALCULATOR This calculator can determine the resistance of up to 10 resistors in parallel. And if the total current is higher, the overall resistance must be lower. $$\frac{1}{R_{EQ}} = \frac{1}{R_{1}} +  \frac{1}{R_{2}} +  \frac{1}{R_{3}} + ... + \frac{1}{R_{N}}$$, When you have only two resistors in parallel: $$R_{EQ} = \frac{R_1\times R_2}{R_1+R_2}$$. Simply input how many resistors you have in parallel and the resistance value of each in the unit of Ohms. Impedance of R and L in parallel Calculator .
