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. To avoid confusion between
the words "resistor" (the electrical component) and "resistance"
(the physical term), the modules are first referred to as the
50 Ω and the 100 Ω module.
- 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

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.
