Electric Field Calculator

Calculate the electric field created by a point charge. The field represents the force per unit charge at any point in space.

E = k × Q / r²

k = 8.99×10⁹ N⋅m²/C² (Coulomb's constant). E points away from positive charges, toward negative charges.

What is electric field?

Electric field E = F/q, the force per unit charge. It describes how a charge would experience force at any point in space.

How are E and V related?

E = -dV/dr. The electric field points from high to low potential. V = kQ/r for a point charge.
