Principle

With the first experiment, an introduction to this topic, the
function of a series resistance is explained as motivation for the
quantitative examination of the law of voltage in series
connections.
A variant of this introductory experiment, based on a chain of
electric Christmas tree lights, could be the preparation of a model
of such a light chain with two identical filament lamps
(4 V / 0.04 A).

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 an electrical device be operated at a higher voltage
than its rated voltage?

Examine the voltage conditions in a series connection of
technical resistances in unbranched circuits.
