As shown in the cutaway view of the lead-acid battery in figure "A" of the illustration, if one-half of the battery's cells are revealed by the cutaway section (with the other half remaining hidden from view), what is the nominal output voltage of the battery? Illustration EL-0031
• Look closely at figure A and count how many separate battery cells are actually visible between the cell dividers. • Recall the nominal voltage of one lead‑acid cell and how total battery voltage is found by adding cell voltages in series. • Remember that the question says only one‑half of the cells are visible in the cutaway, so the full battery has twice that many cells.
• From the illustration, how many distinct cell sections (between dividers, with their own positive/negative plates) can you see in the cutaway portion? • If each of those cells has the standard nominal voltage for a lead‑acid cell, what is the voltage of the visible half, and what does that tell you about the total battery voltage when you include the hidden cells? • Which answer choice matches the total series voltage of all the cells, not just the ones you can see?
• Be sure you are counting cells, not individual plates inside a cell. • Verify you are using the correct nominal voltage for one lead‑acid cell (in volts per cell). • Double‑check that you multiplied the voltage of one cell by the total number of cells in the entire battery, not just the visible half, before matching an answer choice.
