Principle

Conducting spheres with different diameters are charged electrically. The static potentials and the accompanying electric field intensities are determined by means of an electric field meter with a potential measuring probe, as a function of position and voltage.

Benefits


Supplies non-hazardous high voltage

Loss-less measurement of electric field strength

High-sensitive electric field meter also suitable for electrostatic measurement of voltages


Tasks


For a conducting sphere of diameter 2R = 12 cm, electrostatic potential is determined as a function of voltage at a constant distance from the surface of the sphere.

For the conducting spheres of diameters 2R = 12 cm and 2R = 4 cm, electrostatic potential at constant voltage is determined as a function of the distance from the surface of the sphere.

For both conducting spheres, electricfield strength is determined as a function of charging voltage at three different distances from the surface of the sphere.

For the conducting sphere of diameter 2R = 12 cm, electric field strength is determined as a function of the distance from the surface of the sphere at constant charging voltage.
