# Parallel Resistor Calculator

Last Updated on April 7, 2024

We bring you an easy to use calculator to Calculate the equivalent resistance value parallel Resistors, this calculator helps you to calculate up to six Resistors connected in parallel.

We know that every Resistor will have some tolerance value, ex. 100Ω with (+/-) 10% Tolerance will have practical value between 90Ω to 110Ω. Hence if you want to know the precise value of two or more parallel Resistors Value then consider the tolerance value also. (You can use digital multimeter to get the exact value of each resistor with tolerance and then put the Value in the calculator field to get final result). If that much precision is not required then directly place the value and get result in the following parallel circuit resistance calculator.

## Parallel Resistor Calculator

Total Resistance:

When you are in urge to know the total resistance of a parallel resistors or trying to get particular Resistance value by connecting Resistors in parallel, you can use this online Parallel Resistor Calculator, This will support up to 6 parallel resistor values, beyond that you should calculate manually ( just kidding - who use more than six parallel Resistors ) In the first Number of Resistors drop down list choose the number of parallel resistors you want to calculate. Enter the value of each Resistor in the field then hit the Calculate button and you will get the Result in ohms Ω.

## How to Calculate Total Resistance of Parallel Resistors?

By using Ohm's Law we can Calculate parallel Resistance vale, As we know the Voltage (V) is Same in the parallel Resistors. But the Current (I) gets divided in each branches.

To Calculate Total Resistance Rtotal in parallel circuit,

To Calculate Total Current in parallel circuit,

Parallel Resistors are used in many ways,

• To get Desired Resistance Values.
• To form Voltage Divider
• To limit the following of Current
• To get Signal Attenuation
• even more...,
