Principle

The students have already learned how to handle ammeters and
voltmeters, without knowing how they function.
Now, in this experiment, they are to work out the construction and
working principles of a galvanometer.

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 does an instrument for measuring current function?

Construct a model of a galvanometer (current measuring
instrument) and use it to investigate how a galvanometer works.
