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 still does connect Lake Erie with the Hudson River. Indirectly, the Erie Canal connects the Great Lakes with the Atlantic Ocean. The Hudson River, after meeting the east end of the canal, flows to the Atlantic Ocean by way of New York City. The Erie Canal is one of several such connections that enable ocean-going shipping to access Great Lakes ports.
