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 UC, 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. Scope of delivery |
