What is the total voltage of two lead-acid twelve-volt batteries connected in series?

• A. Thirteen volts
• B. Twenty-volts
• C. Twenty-four volts
• D. Thirty volts

Answer: (C)

When two lead-acid twelve-volt batteries are connected in series, their voltages add together. Each battery provides a nominal voltage of twelve volts, so when they are connected in series, the total voltage is calculated by simply adding the individual voltages of the batteries. In this scenario, if one battery has a voltage of twelve volts and the second battery also has a voltage of twelve volts, the total voltage output will be: 12 volts + 12 volts = 24 volts. Thus, when connected in series, the combined voltage of the two batteries amounts to twenty-four volts. This principle of adding voltages applies to batteries in series and is fundamental in electrical engineering, especially in power systems where higher voltage is often required for efficient operation. The other choices provide values that do not represent the correct method of combining the voltages of batteries in series or misunderstand the voltage capabilities of lead-acid batteries. Therefore, the answer is twenty-four volts.
