## Resistors in Parallel - Definition

A Circuit is said to be connected in Parallel if it shares the same voltage across the resistors. In these kind of circuits current is distributed out and combines when they meet at a common point. Units for Resistance are Ohms. 1 Ohm is defined as the electrical resistance between two points when applied on a potential difference of 1 volt, results in a current of 1 Ampere.

### Resistors in Parallel Formula

Equivalent Resistance for a Parallel Circuit is given by the formula 1/R = 1/R₁ + 1/R₂ +... + 1/Rn • R is the Equivalent Parallel Resistance
• R₁, R₂, ... Rn are the resistances of individual resistors starting from 1, 2, 3....n

### How to Calculate Parallel Resistance?

Follow the simple measures provided below to calculate Parallel Resistance. They are in the following fashion

• Firstly, determine the resistances of individual resistors.
• Then find the reciprocal values of all the resistors.
• Take the summation of all the reciprocal values of the individual resistors using the formula i.e. 1/R = 1/R₁ + 1/R₂ +... + 1/Rn
• Simplify the equation after substituting the known values and get the equivalent resistance value in no time.

### FAQs on Parallel Resistor Calculator

1. What happens when you put resistors in Parallel?

When More and More Resistors are added in Parallel to a Circuit the Equivalent Resistance of a Circuit Decreases and Total Current of a Circuit Increases.

2. Why do Resistors in Parallel have Less Resistance?

In a Parallel Circuit net resistance decreases since more components are added and there are more paths for current to pass through.

3. How to Calculate Equivalent Resistance in a Parallel Circuit?

The Formula for Equivalent Resistance in Parallel Connection is given by 1/R = 1/R₁ + 1/R₂ +... + 1/Rn

4. How would you find the Resistance of a Parallel Circuit with n Identical Resistors?

You can find the Resistance of a Parallel Circuit by simply taking the summation of reciprocal of all the n resistances.
