Prior to this experiment, you can first pose the question of how
electrical household appliances are connected. Generally some of
the students know that this is a case of parallel connection.
While a fitting theoretically founded prediction on the total
current can be expected from most students - provided they have
the correct picture of electrical current - a statement on the
total resistance can only be obtained by an experiment.
- 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
How can the total current and resistance in a parallel
connection be calculated?
Examine the relationship between the total current and the
partial currents, and between the total resistance and the partial
resistances, in a parallel connection.
