Principle

From the experimentally determined relationships ∼ I with ρ and A constant, and ∼ 1∕A with ρ and l constant as well as R ∼ lA the equation R = ρ  × lA was worked out and resistivity was introduced as a material "constant". The students should use this equation to experimentally determine the quantity ρ for common conductor materials.

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 high is the resistivity of some metals?

Determine the resistivity of copper, iron and constantan.
