Principle

Metal spheres with different radii and a spherical capacitor are charged by means of a variable voltage. The induced charges are determined with a measuring amplifier. The corresponding capacitances are deduced from voltage and charge values.

Benefits


Supplies non-hazardous high voltage

Several conductive spheres included

Clever investment: The included universal measuring amplifier can also be used for other applications


Tasks


Determination of the capacitance of three metal spheres with different diameters.

Determination of the capacitance of a spherical capacitor.

Determination of the diameters of each test body and calculation of their capacitance values.
