Two 12-volt batteries connected in series will provide how many volts of DC power?

12 volts
18 volts
24 volts
36 volts

The correct answer is: 24 volts

When two 12-volt batteries are connected in series, the total voltage output is the sum of the voltages of each battery. In a series configuration, the positive terminal of one battery is connected to the negative terminal of the other, which allows their voltages to be added together. Since each battery provides 12 volts, combining them in this manner gives: 12 volts + 12 volts = 24 volts. Thus, the correct answer of 24 volts reflects the correct arithmetic of adding the voltages in a series circuit. This principle is fundamental in electrical circuits where batteries are connected in series to achieve a higher voltage output than a single battery can provide.
