Franklin's electrostatic machine on display at the Franklin Institute. Franklin's electrostatic machine is a high-voltage static electricity-generating device used by Benjamin Franklin in the mid-18th century for research into electrical phenomena.
Priestley's famous text supported the distribution of Franklin's research, which helped it becoming one of the most important works on electricity in the late 18th century. [4] Joseph Priestley's electrical machine, illustrated in the first edition of his Familiar Introduction to Electricity (1768)
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
Experiments and Observations on Electricity is a treatise by Benjamin Franklin based on letters that he wrote to Peter Collinson, who communicated Franklin's ideas to the Royal Society. [ 1 ] [ 2 ] The letters were published as a book in England in 1751, and over the following years the book was reissued in four more editions containing ...
His experimental apparatus, known as the "weather machine” predated Benjamin Franklin's more widely recognized experiments. [citation needed] Franklin, unaware of Diviš's work, independently developed and popularized his own lightning rod design, which became widely adopted across Europe and North America. Franklin's contribution ...
Italian physicist and electrical engineer Galileo Ferraris publishes a paper on the induction motor, and Serbian-American engineer Nikola Tesla gets a US patent on the same device [4] [5] 1890: Thomas Alva Edison invents the fuse: 1893: During the Fourth International Conference of Electricians in Chicago, electrical units were defined 1893
In the 1740s and 1750s, the first electrostatic motors were developed by Andrew Gordon and by Benjamin Franklin. Today the electrostatic motor finds frequent use in micro-mechanical ( MEMS ) systems where their drive voltages are below 100 volts, and where moving, charged plates are far easier to fabricate than coils and iron cores.
In 1746–1748, Benjamin Franklin experimented with charging Leyden jars in series, [23] and developed a system involving 11 panes of glass with thin lead plates glued on each side, and then connected together. He used the term "electrical battery" to describe his electrostatic battery in a 1749 letter about his electrical research in 1748.
