Question 152Electricity & Electronics - QMED

The correct answer is B) 2 volts. The nominal open-circuit voltage of one fully charged lead-acid battery cell is approximately 2 volts. This is a well-established fact about lead-acid battery chemistry and design. Lead-acid batteries consist of multiple cells connected in series, with each cell producing around 2 volts when fully charged. The other answer choices are incorrect. 1.5 volts is the nominal voltage of a single alkaline or nickel-cadmium cell, not a lead-acid cell. 6 volts and 12 volts are the typical voltages for lead-acid battery systems, which consist of multiple 2-volt cells connected in series, not the voltage of a single cell.
