Introducción a la Ley de Coulomb

Introduction to Charles-Augustin de Coulomb

Overview of Coulomb's Life and Contributions

• Charles-Augustin de Coulomb was born in Paris, France, on August 23, 1806. He is recognized as a mathematician, physicist, and engineer.

• Coulomb is best known for mathematically describing the law of attraction between electric charges; the unit of electric charge is named after him.

Key Theories and Discoveries

• He contributed to the theory of straight torsion and analyzed soil failure within soil mechanics.

• Coulomb's law states that the force of attraction or repulsion between electric charges is directly proportional to the amount of charge each particle possesses and inversely proportional to the square of the distance separating them.

Demonstration of Coulomb's Law

Practical Experiment

• A simple apparatus was created using a small polystyrene ball covered with aluminum foil, suspended by a copper wire from a cork.

• This setup allows students to easily replicate experiments in class with minimal materials.

Observations During Experiment

• When charged equally, two spheres will not attract each other; they will repel due to having the same charge polarity.
