Question 152Electricity & Electronics - QMED
70% to passThe nominal open-circuit voltage of one cell of a fully charged lead-acid battery is approximately how many volts?
A1.5 volts
B2 volts
C6 volts
D12 volts
AI Explanation
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.
