They are connected in series positive (+) to negative (-) for greater voltage, or in parallel (+ to + and-to -) for greater current capacity. The individual cells inside a 9-volt battery. An everyday examples of a battery is the 9-volt transistor battery, which is six 1.5-volt cells in series.
Definition of Erie Canal. Definition: The Erie Canal was the nation's first Important transportation system connecting the Atlantic Ocean, via the Hudson River in Albany, eastern New York, with Lake Erie. The Erie Canal stretched for 363 miles providing the first waterway connecting the Great Lakes with the Atlantic Ocean.
In the early 1800s, most Americans moved themselves and their goods by water, rather than on the nationâs rough, limited roads. To extend the waterâs reach into the nationâs interior, they began decades of canal building. The Erie Canal was the nationâs most successful example. Built between 1817 and 1825 to link Lake Erie to the Hudson River and New York City, the canal brought together goods and people from across New York State and from the far reaches of the Great Lakes.
