This electric field calculator helps you determine the electric field strength generated by a charged object at a certain distance.

## Electric Field Calculator

### How to Use the Electric Field Calculator

To calculate the electric field, input the charge in Coulombs and the distance from the charge in meters, then click the “Calculate” button to get the electric field strength in Newtons per Coulomb (N/C). The result will be displayed instantly.

### How the Calculator Works

The electric field is calculated using Coulomb’s law. The formula to calculate electric field (E) is E = k * q / r^{2}, where *k* is Coulomb’s constant (approximately 8.99 x 10^{9} N·m²/C²), *q* is the charge in Coulombs, and *r* is the distance from the charge in meters. Our calculator automatically computes the electric field using these values.

### Limitations

This calculator assumes a point charge in a vacuum and does not account for other factors that may be present in a real-world situation, such as dielectric materials or other nearby charges. It is intended for educational purposes and not for complex physics simulations or electrical engineering work where more sophisticated calculations are necessary.
