Principle
The resistance of a short thick wire is different to that of a long thin one.
Benefits
- Flexible experimenting thanks to wireless data transmission
- No additional cable connections between the building blocks needed - clear arranged and quick setup
- Contact safety due to puzzle blocks system
- Corrosion-free gold plated contacts
- Doubled earning success: Electric circuit diagram on top, real components from below
Tasks
Examine how the value of the resistance of a wire depends on its length and cross-sectional area.
