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.
The Erie canal was very important because, when the Erie canal wasn't built yet, it was hard for transportation and trading. However when the Erie canal was built, it was much easier to go from 1 place to the other, and to get or give goods to other places. Meaghan Anderson.
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.
