Driving a water wheel

Principle

The motion of the water wheel was used in the past mainly in mills, for example, to grind grain.

With a water wheel you could also turn a dynamo. The electrical energy can be used to power different motors, for example, pumps.

Today, huge turbines are used to generate ...

Voltage and current in a series connection of solar cells

Principle

The pupils should examine a connection in series of two solar cells by measuring the open circuit voltage, Uges, and the short-circuit current,  Iges.

Greater voltages can be reached by connecting solar cells in series.

In addition, the voltages at both solar cells, U1 ...
