Electrostatic torsion balance, after Coulomb

1876

One of the classic experiments in the field of electrostatics is the experiment that was carried out by the French researcher Charles Augustin Coulomb (1736-1806) around 1785. To his name is the famous law of attraction and repulsion of two electric charges, which states the connection between the electrostatic force, the magnitude of both charges, and the distance between the charges. This law has become so famous, because its mathematical formulation looks exactly like Newton's law of gravitation.

This torsion balance or deflection balance can be used to check Coulomb's law. After the application of an electric charge, the silver thread in the glass cylinder will distort. The angular distortion can be read from a scale and is a measure for the electric force.
