The resistivity of wires Principle From the experimentally determined relationships R ∼ I with ρ and A constant, and R ∼ 1∕A with ρ and l constant as well as R ∼ l∕A the equation R = ρ × l∕A 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
