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 1836 an enlargement program commenced on the main Erie Canal system. The canal was straightened a bit, the channel was increased in size to 7â² x 70â², and the locks were enlarged to 18â² x 110â². This permitted boats of much greater size on the Erie, Champlain, Cayuga-Seneca and Oswego canals, and further diminished the importance of the smaller lateral canal.
