Principle

After the students have recognised that there are also conducting liquids, namely aqueous solutions of electrolytes, the question whether Ohm's Law is also valid for them is to be answered.
The experimental results affirm that this is true. The students should be subsequently informed that, however, this is not the case for all solutions of electrolytes.

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

Is Ohm's Law also valid for conduction processes in liquids?

Prepare an aqueous solution of copper sulphate and examine the relationship between voltage and current when current passes through it.
