Question 238Electricity & Electronics - Assistant Engineer

The correct answer is A) 1.2 volts. Nickel-cadmium (NiCd) batteries have a nominal voltage of approximately 1.2 volts per cell. This is an established standard for NiCd battery technology and is specified in various marine and electrical engineering regulations and guidelines. The other answer choices are incorrect because 1.5 volts is the nominal voltage for a lead-acid battery cell, 2.0 volts is too high for a single NiCd cell, and 3.0 volts is the nominal voltage for a lithium-ion battery cell, which is a different chemistry than the NiCd batteries commonly used in marine applications.
