Description

Voltage, Energy and Force The electrical terrain is just as varied as any geographic landscape - and equally one that we need science to navigate effectively, without wasting our energy. In this program we look at voltage, energy and force which determines when electricity is dangerous or benign. We demonstrate the electric potential and its gradient, the potentials of atoms and metals, electric energy, and why sparks jump. A most enlightening program. The Electric Battery In the 18th century, electricity was just a curiosity. But in the 19th century it became one of the most important tools not only of science but of industry. In this program we meet the remarkable Alessandro Volta, inventor of the electric battery, using the internal properties of different metals to turn chemical energy into electrical energy. Electric Circuits Learning to harness and control the flow of water has been a critical ingredient in the development of civilisation. In many ways it mirrors the development
