The students should first derive Ohm's law I ∼ U from their measured values. Then they should find out that R = const. is the condition for the validity of this law.
- 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
What is the relationship between voltage and current?
Take a series of pairs of voltage and current measurements in a circuit and use these to determine the relationship between U and I.
