Principle
Working out the equation R = ρ l∕A takes some time. The relationships R ∼ l and R ∼ 1∕A should first be recognized. We recommend that each group of students only carry out one of the experiments, and following this, gain the knowledge that R ∼ l∕A in a joint evaluation.
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
