[12] [13] The prefix tribo-(Greek for 'rub') refers to sliding, friction and related processes, as in tribology. [14] From the axial age (8th to 3rd century BC) the attraction of materials due to static electricity by rubbing amber and the attraction of magnetic materials were considered to be similar or the same. [11]
In his book, he also studied static electricity using amber; amber is called elektron in Greek, so Gilbert decided to call its effect the electric force. He invented the first electrical measuring instrument, the electroscope, in the form of a pivoted needle he called the versorium. [10]
Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge . The word "static" is used to differentiate it from current electricity , where an electric charge flows through an electrical conductor .
6th century BC – Greek philosopher Thales of Miletus observes that rubbing fur on various substances, such as amber, would cause an attraction between the two, which is now known to be caused by static electricity. He noted that rubbing the amber buttons could attract light objects such as hair and that if the amber was rubbed sufficiently a ...
Ancient Greek philosopher Thales of Miletus described static electricity by rubbing fur on substances such as amber. 1600: English scientist William Gilbert coined the word electricus after careful experiments. He also explained the magnetism of Earth. 1660: German scientist Otto von Guericke invented a device that creates static electricity ...
Distinction between electricity and magnetism. An amber stick when rubbed affects a rotating needle made of any type of metal (a versorium ) and attracts paper, leaves and even water. But electricity is different from heat and to magnetism which only attracts iron-bearing materials (he calls it coition).
In 1600, the English scientist, William Gilbert extended the study of Cardano on electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing amber. [7] He coined the Neo-Latin word electricus ("of amber" or "like amber", from ήλεκτρον [ elektron ], the Greek word for "amber") to refer to ...
[13] [14] This gave Franklin a complete system to experiment with generating and storing electricity. [7] When amber, sulfur, or glass are rubbed with certain materials, they produce electrical effects. [15] Franklin theorized this "electrical fire" was collected from this other material somehow, and not produced by the friction on the object.
