A parallel resistor is a type of electrical circuit in which two or more resistors are connected side-by-side, with each resistor having its own path for the flow of electric current. In a parallel resistor circuit, the total resistance is less than the value of the smallest resistor in the circuit, because the current can flow through multiple ...
It is because when we add a new resistor in parallel, it opens a new way to pass the current so the total current after adding the new resistor is higher than the previous value, hence the total resistance is always lower than the previous one. The formulae to calculate the total resistance in parallel, is as follows: 1/R Total =1/R 1 +1/R 2 +1 ...

Each resistor in a parallel design has the same voltage applied to it, but the circuit’s total current is distributed among the resistors according to their unique resistances. The main goal of parallel resistance is to change the total resistance that the power source perceives in an electrical circuit by offering different paths for current ...
In an electrical network containing parallel resistors, the current of the whole circuit would be equivalent to the sum of all the currents flowing through each single resistor. Parallel Resistance Formula: Our free parallel resistor calculator uses the following equation to calculate the resistor value in seconds:
The lower resistance resistor will have a larger impact on the total parallel resistance, making the total resistance closer to the value of the lowest resistor. This calculator streamlines the process of determining parallel resistance, offering a practical tool for students, engineers, and hobbyists involved in circuit design and analysis.
where: R R R is the total or equivalent parallel resistance;; R 1, R 2,..., R n R_1, R_2, ..., R_n R 1 , R 2 ,..., R n are the resistances of the resistors 1st resistor, 2nd resistor, up to the nth resistor in the circuit. We derived that formula from the concept that the sum of the currents passing through parallel resistors is equal to the electric current from the voltage source.

Parallel Resistor Formula. When multiple resistors are added to a circuit in parallel the total resistance can be found using this formula. 1 / R T = 1 / R 1 + 1 / R 2 + … + 1 / R n. Thus, the reciprocal of the total resistance of resistors connected in parallel is the sum of the reciprocal of each resistance.
Imagine we have a four-resistor setup (R₁ = 20 Ω, R₂ = 40 Ω, R₃ = 80 Ω, R₄ = 100 Ω), and we need to know how the current divides into each branch when we arrange them in parallel.Let's say the source current (I) equals 1 A.Here is how our current division calculator works: Select the Resistive circuit type. It's a default option.
Here are the steps to follow for using this equivalent resistance calculator or parallel resistance calculator: First, enter the value of Resistor 1.

The voltage across each parallel resistor is the same. Hence, the voltage across the \({6}\Omega\) resistor = 6.39 V. ... Record voltage, current and calculate resistance.
R n is the resistance value of each resistor. How to calculate parallel resistor. When you connect resistors in parallel, each component has the same voltage source or shares the same voltage. Depending on each resistor's resistance value, the amount of current that flows through them can be found using Ohm's law formula.
