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.
Construction on the Erie Canal began in 1817 and cost over $7 million to build. The Erie Canal was 363 miles in length and was opened on Oct. 26, 1825. In 1825, it took five days to travel the length of the canal, which took two weeks by stagecoach. The Erie Canal allowed New York City to become the largest city and port at the time giving the state more political influence.
