Electric Field Calculator

Find the electric field from a point charge.

Electric field (N/C) 35,950.21

Formula: E = k·Q ÷ r²

Step-by-step with your numbers:

1. Values used:

2. Charge = 0 C

3. Distance = 0.5

5. Electric field = 35,950.21N/C

Did we solve your problem today?

A point charge creates an electric field that weakens with the square of distance.

The math behind it

E = k·Q ÷ r², with Coulomb's constant k ≈ 8.99 × 10⁹ N·m²/C².

1 µC at 0.5 m → about 35,950 N/C.

How is field related to force?

Force on a test charge q is F = qE.
