Principle

Working out the equation R = ρ lA 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 ∼ lA 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.
