Electric Charge
Amber is a yellowish, translucent mineral. As early as 600 BC the
Greek philosopher, Aristophanes was aware of its peculiar property:
when rubbed with a piece of fur, amber develops the ability to attract
small pieces of material such as feathers. For centuries this
strange, inexplicable property was thought to be unique to amber.
This strange effect remained a mystery for over 2000 years, until,
around AD 1600, Dr William Gilbert investigated the reactions of
amber and magnets and first recorded the word 'Electric' in a report
on the theory of magnetism.
Later in, in 1895, H.A. Lorentz developed the Electron Theory. We
now know that there are three ways to generate electricity: Static,
Electrochemical and Electromagnetic Induction.
