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.
The Erie Canal is a canal in New York that is part of the east-west, cross-state route of the New York State Canal System (After a later conversion, became known as the New York State Barge Canal). Originally, it ran about 363 miles (584 km) from Albany, on the Hudson River, to Buffalo, at Lake Erie.
