Protection from electricity

Electricity is the general term for all phenomena caused by electric charge, at rest or in motion. Electric charge is carried by negatively charged electrons and positively charged protons and ions.

Electric charge moves in electric conductors by motion of free electrons and in liquids by movement of ions. One distinguishes between conductors, non-conductors and semiconductors.

The most spectacular form of electricity is lightning, in which high electrostatic charge caused by friction is released. Electricity is vital to our everyday lives. Light, heat and power need to be available at all times. Due to the growing importance of communication and information technology, electricity today can be seen as the backbone of civilisation.
