The resistance of wires - dependence on the length andcross-section 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 How do the length and cross-sectional area of a wire influence the value of its resistance? Determine the relationship between the resistance of a wire and its length and cross-sectional area. Scope of delivery |
