# Electric Field calculator

## How to use electric field calculator?

Are you a student of physics and looking for an online tool that can make your electric field calculation task easy to go? Look no further we have made an electric field calculator for you, the calculator can calculate any kind of electric field. just enter the charge in Columb, for more convenience we have assigned different units of charges like columb and microcolumn. In 2nd label enter the distance from the charge, click the calculate button and the electric field tool will display the result for you.

## What is the Electric Field?

The electric field is the force is the force of attraction or repulsion created by a single charge, The electric field can be positive or negative. The positive electric field is created by a proton while the negative electric field is created by an electron. In either case, the electric field is quantized, and each electric and proton creates equal electric field but in the opposite direction which is equal to e=1.6×e-19. C. You can calculate positive or negative electric field with the above electric field calculator

## Formula to calculate electric field

The formula to calculate Electric Field (\(E\)) is:

\[ E = k \times \frac{q}{{r^2}} \]Where:

- \(E\): Electric Field
- \(k\): Coulomb's constant (\(8.988 \times 10^9 \, \text{N m}^2/\text{C}^2\))
- \(q\): Charge
- \(r\): Distance

Example: Suppose the charge (\(q\)) is 2 Coulombs and the distance (\(r\)) is 3 meters. Calculate the Electric Field.

**Answer:**

Using the Electric Field formula:

\[ E = 8.988 \times 10^9 \times \frac{2}{{3^2}} \]Calculating the result:

\[ E \approx 2 \times 10^9 \, \text{N/C} \]Therefore, the Electric Field is approximately \(2 \times 10^9 \, \text{N/C}\).
