In Figure 9 we see a pair of 12-volt batteries connected in parallel. This 12-volt battery pack is connected to a single 12-volt charger. Note the blue wire designated W1. The purpose of this wire is to balance the voltage drop evenly across both batteries and each wire during charging.
Confidence votes 36. The Erie Canal was so important to the United States (U.S) because it was the water way connecting the Hudson River with Lake Erie through New York State. 20 people found this useful.
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.
