electronics.coulombs_law.couloumbs_law(force: float, charge1: float, charge2: float, distance: float) → dict[str, float]¶

Apply Coulomb’s Law on any three given values. These can be force, charge1, charge2, or distance, and then in a Python dict return name/value pair of the zero value.

Coulomb’s Law states that the magnitude of the electrostatic force of attraction or repulsion between two point charges is directly proportional to the product of the magnitudes of charges and inversely proportional to the square of the distance between them.
