Determining the capacitance of a sphere in free space

Determining the capacitance of a sphere in free space

P3.1.6.1:

The experiment P3.1.6.1 determines the capacitance of a sphere in a free space by charging the sphere with a known high voltage U and measuring its charge Q using an electrometer amplifier connected as a coulomb meter. The measurement is conducted for different sphere radii r. The aim of the evaluation is to verify the proportionalities
