Question 28Electricity & Electronics - 1st Asst/Chief

The correct answer is C) 24 volts and 150 ampere-hours. To determine the terminal voltage and ampere-hour capacity of the battery bank, we need to consider the configuration of the batteries. If each battery is rated at 12 volts and 75 ampere-hours, and they are connected in series, the terminal voltage of the battery bank will be the sum of the individual battery voltages, which is 24 volts. The ampere-hour capacity of the battery bank will be the same as the individual battery capacity, which is 75 ampere-hours. Therefore, the correct answer is 24 volts and 150 ampere-hours. The other options are incorrect because: A) 12 volts and 150 ampere-hours is incorrect, as the terminal voltage would be 12 volts, not 24 volts. B) 24 volts and 75 ampere-hours is incorrect, as the ampere-hour capacity would be 75 ampere-hours, not 150 ampere-hours. D) 48 volts and 300 ampere-hours is incorrect, as the terminal voltage would be 48 volts, not 24 volts.
