Levi Strauss & Co. (/ ˈ l iː v aɪ ˈ s t r aʊ s / LEE-vy STROWSS) is an American clothing company known worldwide for its Levi's (/ ˈ l iː v aɪ z / LEE-vyze) brand of denim jeans.It was founded in May 1853 [9] when German-Jewish immigrant Levi Strauss moved from Buttenheim, Bavaria, to San Francisco, California, to open a West Coast branch of his brothers' New York dry goods business.
Levi Strauss was never married, and died on September 26, 1902 in San Francisco. His estate was worth about $30 million (equivalent to $855 million in 2023). [1] Levi's nephew Sigmund Stern's only child, Elise Fanny Stern, [19] married Walter A. Haas, the son of Abraham Haas, whose descendants are the current owners of Levi Strauss & Co. [20]
German scientist Otto von Guericke invented a device that creates static electricity. This is the first ever electric generator. 1705: English scientist Francis Hauksbee made a glass ball that glowed when spun and rubbed with the hand 1720: English scientist Stephen Gray made the distinction between insulators and conductors. 1745

Electric current can flow through some things, electrical conductors, but will not flow through an electrical insulator. [ 42 ] By historical convention, a positive current is defined as having the same direction of flow as any positive charge it contains, or to flow from the most positive part of a circuit to the most negative part.
The first three-phase alternating current power transmission at 110 kV took place in 1907 between Croton and Grand Rapids, Michigan. Voltages of 100 kV and more were not established technology until around 5 years later, with for example the first 110 kV line in Europe between Lauchhammer and Riesa, Germany, in 1912.

In electronics, the relationship between the direct current (DC) through an electronic device and the DC voltage across its terminals is called a current–voltage characteristic of the device. Electronic engineers use these charts to determine basic parameters of a device and to model its behavior in an electrical circuit. These ...
