Question 151Electricity & Electronics - QMED
70% to passHow many cells are within a 24 volt lead-acid battery?
Athree cells
Bfour cells
Csix cells
Dtwelve cells
AI Explanation
The correct answer is D) twelve cells. A 24 volt lead-acid battery is composed of twelve individual 2-volt cells connected in series to create the 24 volt system. This is the standard configuration for a 24 volt lead-acid battery as specified by maritime regulations and safety guidelines for the US Coast Guard Captain's License examinations. The other answer choices are incorrect because a 24 volt system would not have only 3, 4, or 6 cells - that would result in voltages much lower than 24 volts. Twelve cells connected in series is the proper design to achieve the 24 volt output required for many marine applications overseen by the US Coast Guard.
