Principle

A red light-emitting diode requires approximately 2 V supply
voltage, that means it cannot be operated with a single solar cell.
The Pupil kit contains a solar battery which supplies the required
voltage. The experiement should make clear how single solar cells
can be combined so that they generate the same voltage as the solar
battery: They have to be switched on in a row, so that their
voltages can be added to each other. The solar battery uses the
same principle.

Benefits


Experiment is part of a complete solution set with a total of 26 experiments for Renewable Energy solar cells, wind power, water power

Safe experimentation: the lamp is protected against touch, the housing is well ventilated with the aid of holes and is only slightly heated

The power supply used is versatile and is particularly suitable for pupil tests for all ages
