Charging and discharging a capacitor

Principle

The students know that the electrical component "capacitor" can store electrical energy.
The first experiment concentrates on the change in the capacitor voltage over time during charging and discharging. Qualitative statements are first derived, then the change in the voltage during charging and discharging is quantitatively determined.
The second experiment deals with semi-quantitative relationships between the capacitor voltage U_C, the charging resistance R, the capacity of the capacitor C and the time taken for the charging process t.

Benefits

• No additional cable connections between the building blocks needed - clear arragned and quick setup
• Contact saftey due to puzzle blocks system
• Corrosion-free gold plated contacts
• Doubled earning sucess: Electric circuit diagram on top, real components can be seen unterside

Tasks

How does the capacitor charging/discharging process take place?

Examine how the voltage changes during the charging and discharging of a capacitor, and also determine on which factors the rate of these processes are dependent and the effects they have.
