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
AI Explanation
The correct answer is C) 12 volts.
The nominal output voltage of a lead-acid battery is determined by the number of cells in the battery, with each cell producing approximately 2 volts. Since the illustration shows that one-half of the battery's cells are revealed, and a lead-acid battery typically has 6 cells, the nominal output voltage of the battery would be 6 cells x 2 volts per cell = 12 volts.
The other answer choices are incorrect because 6 volts would represent a battery with only 3 cells, 7.5 volts would not be a standard lead-acid battery voltage, and 18 volts would be too high for a typical lead-acid battery.
