What happens to voltage when three 12-volt batteries are connected in series?

12 volts
24 volts
36 volts
48 volts

The correct answer is: 36 volts

When three 12-volt batteries are connected in series, the total voltage is calculated by adding the voltages of each individual battery together. In this case, each battery contributes 12 volts, so you add 12 volts + 12 volts + 12 volts. This results in a total voltage of 36 volts. This series connection allows the voltage to increase while the capacity in ampere-hours remains the same as that of a single battery. Therefore, connecting three 12-volt batteries in series effectively creates a system with a combined voltage of 36 volts, making this the correct answer.
