Principle

Transformers represent a significant application of induction. They are predominately used to transmit electrical energy over long distances with as little loss as possible, or to adjust fixed supply voltages to the rated voltages of electrical appliances and equipment.
The students know that an induction voltage can also be generated without movement of the field and induction coils relatively to each other, because it only requires that the induction coil contains a part of a changing magnetic field. They will therefore understand the working principle of a transformer without any great difficulty.

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 a given alternating voltage be increased or reduced?

Set up a model of a transformer, use it to increase and reduce given alternating voltages and examine which conformity to law is given.
