Question 95Electricity & Electronics - Assistant Engineer

The correct answer is B) 2 volts. The nominal open-circuit cell voltage of one lead-acid storage battery cell is 2 volts. This is a standard specification for lead-acid battery cells, which are commonly used in marine applications. The voltage of a single lead-acid cell is determined by the electrochemical reactions that occur within the cell during charging and discharging, and the nominal 2-volt value is a well-established industry standard. The other options are incorrect because 1.2 volts is the nominal voltage for a nickel-cadmium (NiCd) battery cell, 6 volts is the total voltage of a lead-acid battery pack with 3 cells in series, and 12 volts is the total voltage of a lead-acid battery pack with 6 cells in series, which is a more common configuration for marine applications.
