Between 1884 and 1885, Hungarian engineers Zipernowsky, Bláthy, and Déri from the Ganz company in Budapest created the efficient "Z.B.D." closed-core coils, as well as the modern electric distribution system. The three had discovered that all former coreless or open-core devices were incapable of regulating voltage, and were therefore ...
A fun note, in 2010 the Ohio State University student-built Buckeye Bullet 2, a fuel cell vehicle built in collaboration with Monaco-based Venturi Automobiles and equipped with a Ballard fuel cell, set a FIA world speed record for electric vehicles in reaching 307.7 mph (495.2 km/h), eclipsing the previous record of 245.5 mph (395.1 km/h). The ...
An electrical grid (or electricity network) is an interconnected network for electricity delivery from producers to consumers. Electrical grids consist of power stations , electrical substations to step voltage up or down, electric power transmission to carry power over long distances, and finally electric power distribution to customers.
The war of the currents was a series of events surrounding the introduction of competing electric power transmission systems in the late 1880s and early 1890s. It grew out of two lighting systems developed in the late 1870s and early 1880s: arc lamp street lighting running on high-voltage alternating current (AC), and large-scale low-voltage direct current (DC) indoor incandescent lighting ...

The Energy Policy Act of 1992 required transmission line owners to allow electric generation companies open access to their network [3] [4] and led to a restructuring of how the electric industry operated in an effort to create competition in power generation. No longer were electric utilities built as vertical monopolies, where generation ...
Electric power distribution is the final stage in the delivery of electricity. Electricity is carried from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 33 kV with the use of transformers. [1]
The Ohio State University football team won the national championship in 2002 and 2014, and consistently competes for the prize annually. The Cincinnati Reds won the World Series baseball championship in 1990 following their run as the Big Red Machine in the 1970s. The team won the National League Central Division champions in 2010 and 2012.
