Transformer with Cobra SMARTsense

Article no: P6006969

Principle

The transformer usually consists of two or more coils of insulated copper wire wound on a common iron core. The transformer changes the input AC voltage applied to one coil into the output AC voltage which can be tapped at the other coil. The ratio between input and output voltage corresponds to the ratio of the number of turns of the primary and secondary coils.

Benefits

  • Simple design of all components so that students can easily see their function
  • The functional models can be built up successively, thus the functional relationships between the individual components are well understood.
  • No tools necessary
  • Especially understandable and didactically prepared description of the experiment (reference to everyday life etc.) including protocol questions.
  • Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
  • Increased motivation of students by using the intuitive measureAPP.
  • Increased media competence.

Tasks

In this experiment, the students are to create a transformer from two resting electromagnets (coils) connected by an iron core and to study and learn about the properties of this transformer.

Learning Objectives

This experiment is to demonstrate the principle and one of the benefits of a transformer.
