Principle

Damaged leads or defective electrical equipment can lead to short-circuits. The actual piece of electrical equipment - or more accurately, its resistance - are hereby circumvented. The result is an inadmissibly high current, which can cause a fire to break out because of the resulting excessive heating up of current-carrying parts.

In this experiment, students should learn the principle on which the simplest and oldest safety device, the safety fuse, functions.

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

How can electrical appliances be protected from catching fire when a short-circuit occurs?

Set up a circuit containing a model of a safety fuse and use it to examine the function of an electric fuse.
