Electrical Phenomenon
1912 3mDocumentary, Short
The electric machine, called a "static machine," which will produce the electricity necessary for our experiments, is composed of two discs of glass turning in opposite directions, and fitted with small copper plates. Metallic brushes touch the copper plates and electrify them; conductors or "combs" fitted with points collect the electricity developed by the passage of the brushes on the copper plates and vivid sparks appear between the balls of the machine. In the experiment of the "Tourniquet," needles with points, which are curved, turn in opposite directions to the points: this is a phenomenon due to the repulsion caused by the electricity passing through these points. An experiment made by Benjamin Franklin is also depicted in this film: A kite, fitted with a metal point, ascends to gather atmospheric electricity from the clouds. If, at the base of the metal cord attached to the kite, we hang a key, the approach of another key causes large sparks to appear. In America, after Franklin's discovery, exaggeration was so great, that umbrellas were fitted with lightning conductors connected with the ground by a metal chain. Another experiment from Faraday is also depicted here: A little bird is protected from the electric discharge, its cage being entirely of metal, by attaching it to the ground with a connecting wire as a conductor. The lightning conductor which leads the electric spark into the earth was discovered by Benjamin Franklin in 1753.
