How to reference this medium
One circuit is shown for the charging process and another for the discharging process. The capacity of the capacitor integrated in the circuit can be varied. Starting with a capacitor with air as the dielectric and a defined area and defined plate separation, the following variations are possible:
• Doubling of the plate separation
• Doubling of the plate area
• Insertion of a glass plate between the capacitor plates
The associated current and voltage curves for the charging and discharging processes can be displayed independently of each other for different capacities.
• Doubling of the plate separation
• Doubling of the plate area
• Insertion of a glass plate between the capacitor plates
The associated current and voltage curves for the charging and discharging processes can be displayed independently of each other for different capacities.
