🔍 Key Concepts

• Trace how the positive and negative terminals of each battery are connected to one another in the diagram. • Compare what happens to voltage and capacity when batteries are in series versus parallel. • Think about what a compound (series-parallel) connection would look like in a four-battery bank.

💭 Think About

• Follow the wiring from the positive terminal of Battery 1 all the way through the bank to see which terminals it ultimately connects to. • Ask yourself: Are any batteries connected positive-to-negative (like a chain), and are any connected positive-to-positive / negative-to-negative (like branches)? • If you grouped the four batteries into two pairs, how would each pair be connected, and how are those pairs then connected to each other?

✅ Before You Answer

• Verify whether each pair of batteries has a positive terminal connected to a negative terminal (a sign of series connection). • Check if there are points where two positives join together or two negatives join together (a sign of parallel connection). • Confirm which two terminals actually go out to the external circuit and whether multiple batteries share those same output polarities.
