🔍 Key Concepts

• Typical voltage produced by one lead-acid cell • Relationship: battery voltage = number of cells × volts per cell • Common nominal voltages: 6V, 12V, 24V and how they’re built from cells

💭 Think About

• First, recall (or look up) the approximate voltage of a single lead-acid cell. • Next, divide 12 volts by the voltage of one cell to estimate how many cells must be connected in series. • Compare your result to the answer choices and see which one matches your calculation.

✅ Before You Answer

• Verify the nominal voltage of a single lead-acid cell (about 2 volts). • Confirm that cells in a battery to increase voltage are connected in series, so voltages add. • Multiply your chosen number of cells by the per‑cell voltage and check that it comes out to approximately 12 volts.
