Capacitance of metal spheres and of a spherical capacitor 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.
Learning objectives - Voltage
- Potential
- Charge
- Electric field
- Electrostatic induction
- Electrostatic induction constant
- Capacitance
- Capacitor
- Dielectrics
