Principle

The students should recognise that a diode acts as an electrical valve. The teacher has to decide, according to the situation, whether an explanation is to be given for this action with the help of a model of the electrical processes within the components, or if this action is merely to be established.

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
