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.
DeWitt Clinton, who was mayor of New York City and later Governor of New York State (1817-22 and 1825-28) had the vision and conviction to build the first 363-mile long Erie Canal. It is interesting to note that the first canal across the state bypassed Lake Ontario and only connected the Hudson River to Lake Erie.
