Coulomb's Potential and Electric Field of Metallic Spheres

Conducting spheres of different diameters are electrically charged. The static potentials and corresponding electric field intensities are determined by computer using an electric field meter with a potential measuring probe, based on position and voltage.

In detail, the proposed tasks are: For a conducting sphere with diameter 2R = 12 cm, the electrostatic potential is determined based on the voltage at a constant distance from the sphere's surface / For conducting spheres with diameters 2R = 12 cm and 2R = 4 cm, the electrostatic potential at constant voltage is determined based on the distance from the sphere's surface / For both conducting spheres, the electric field intensity is determined based on the charge voltage at three different distances from the sphere's surface / For the conducting sphere with diameter 2R = 12 cm, the electric field intensity is determined based on the distance from the sphere's surface at a constant charge voltage.
