Pioneers in Electricity
he phenomenon that Thales had observed and recorded in antiquity aroused the interest of many
scientists through the ages. They made various practical experiments in their efforts to identify the
elusive force that Thales had likened to a "soul" and which we now know to have been static electricity.
Of all forms of energy, electricity is the most baffling and difficult to describe. An electric current cannot be seen.
In fact it does not exist outside the wires and other conductors that carry it. A live wire carrying a current looks
exactly the same and weighs exactly the same as it does when it is not carrying a current. An electric current is
simply a movement or flow of electrons.
The following sections describe some pioneers in the advancement of our knowledge of electricity.
