Parallel Resistor Calculator

Parallel Resistor Calculator

Parallel Resistor Calculator. This calculator will let you calculator the total resistance of a parallel resistor circuit. Simply input how many resistors you have in parallel and the resistance value of each in the unit of Ohms. Then press calculate and it will give you the answer. There are also some worked examples below the tool.

Number of resistors (Minimum of 2 resistors)
Equivalent Resistance (Ω)

Example 1:

Two 10 Ohm resistors are in parallel. What is the total resistance of the circuit?


Example 2:

Three resistors, a 10 Ohm, a 5 Ohm and a 2 Ohm, are in parallel. What is the total resistance?
