A free program for Android, by Statnett.
The app 'Ohm: A Virtual Science Centre' is a science-based learning app about energy and electricity. It provides a comprehensive overview of the various forms of energy, and how they are transferred from one form to another. In addition, it explains how our society is dependent on electricity, and how the development of technology has progressed since the discovery of electricity.
It is based on the idea that everyone is capable of understanding science and technology, even if they have no previous knowledge of science or technology. This idea is supported by the fact that the app is based on well-defined concepts, and that it is filled with interesting and easy-to-understand examples, which everyone can understand.
