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.
Now, the Canalâonce again known as the Erie Canalâis almost entirely used for recreation. At almost 350 miles (540 km) long, 120 feet (37 m) wide, and 12 feet (3.7 m) deep, it remains a feather in New York's cap, and still provides an economic boost by way of tourism.
