Electric Field Calculator

Formula

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

\[ E = k \cdot \frac{Q}{r^2} \]

Where:

\( E \) is the magnitude of the electric field (N/C)
\( k \) is Coulomb's constant, \( 8.9876 \times 10^9 \, \text{N} \, \text{m}^2 / \text{C}^2 \)
\( Q \) is the point charge (C)
\( r \) is the distance (m)

What is an Electric Field?

An electric field is a region of space that exerts a force on charges, which can be either repulsive or attractive. Electric fields are created by electric charges and are fundamental to the theory of electromagnetism.
