Benjamin Franklin did research on electricity in the 18th century Electricity would remain framtid


Lightning is one of the most dramatic effects of electricity. Electricity is a general term that covers a variety of phenomena resulting from the presence and flow of electric charge. These include framtid ov10 easily framtid ov10 recognizable phenomena, such as lightning, static electricity, and the flow of electrical current in an electrical wire. In addition, less familiar concepts include electricity as electromagnetic fields and electromagnetic induction. The word is from the New Latin electricus, framtid ov10 "amber-like" [a], was created in 1600 from the Greek ήλεκτρον (electron) meaning amber (hardened plant resin), because the effects of static electricity produced by rubbing amber classic. Usage In common usage, the word "electricity" is referring to a number of physical effects. In scientific usage, however, the term is not clear, and, related, but distinct concepts better identified by more precise terms: Electric charge: a property of some subatomic particles, which determines their electromagnetic interactions. Electrically charged material is influenced by, and produces, electromagnetic fields. Electric current: a movement or flow of electrically charged particles, typically measured in amperes. Electric field: the effect produced by an electric charge on other expenses in the vicinity. Electric potential: the capacity of an electric field to do work on an electric charge, typically framtid ov10 measured in volts. Electromagnetism: a fundamental interaction framtid ov10 between the magnetic field and the presence and movement of electric charge. The most common framtid ov10 use of "electricity" is less precise word. It refers to: Electric power is supplied commercially by the electrical power industry. In a loose but common use of the term, "electricity" may be used to mean "wired for electricity" which means working connection to an electric power plant. Such a connection grants the user access to "electricity" to the electric field present in electrical wiring, and thus to electric power. Electrical phenomena have been studied since antiquity, though advances in the science were not made until the seventeenth century and eighteenth. Practical applications for electricity however remained few, and will not be until the late nineteenth century that engineers were able to make use of industrial and residential. The rapid expansion in electrical technology at this time to change the industry and society. Tremendous framtid ov10 flexibility Electricity as a source of energy means it can be incorporated into almost framtid ov10 limitless set of applications which include transport, heating, lighting, communications, and computation. Electricity is the backbone of modern industrial society, and is expected to remain so in the foreseeable future. [1] History
See also: Etymology of electricity Long before framtid ov10 there was knowledge of anyone realize electric shocks from electric fish. Ancient framtid ov10 Egyptian text from 2750 BC referred to these fish as the "thunder of the Nile", and described them as the "protectors" of all other fish. Electric fish again reported millennia later by ancient Greek, Roman and Arabic naturalists and physicians. framtid ov10 [2] Several ancient authors, such as Pliny the Elder and Scribonius Largus, evidenced by the numbing effect framtid ov10 of electric shocks delivered by catfish and torpedo rays, and knew that such shocks could travel along the object. [3] Patients suffering from diseases such as gout or head directed framtid ov10 to touch electric fish in the hope that the powerful shocks might heal them. [4] Perhaps the earliest and nearest approach to the discovery of the identity of lightning, and electricity from other sources, should be attributed to the Arabs, who before the 15th century had the Arabic word for lightning (raad) applied to the electric ray. [5] The ancient cultures around the Mediterranean knew that certain objects, such as rods of amber, could be rubbed with cat's fur to attract light objects like feathers. Thales of Miletos made a series of observations on static electricity around 600 BC, from which he believed that friction framtid ov10 is given amber magnetic, in contrast to minerals such as magnetite, which needed no rubbing. [6] [7] Thales believed was not true in the attraction is due to a magnetic effect, but later science framtid ov10 would prove the relationship between magnetism and electricity. According to a controversial theory, the Parthians may have had knowledge of electroplating, based on the 1936 discovery of the Baghdad Battery, which resembles a galvanic cell, although it is uncertain whether the artifact was electrical in nature.

Benjamin Franklin did research on electricity in the 18th century Electricity would remain framtid ov10 little more than an intellectual curiosity for millennia until 1600, when the English scientist William Gilbert made a careful study of electricity and magnetism, distinguishing the lodestone effect from static electricity produced by rubbing framtid ov10 amber. [6] He coined the New Latin word electricus ("amber" or "sep
