Two 1.5-V alkaline batteries connected in series would supply how many volts?

Two 1.5-V alkaline batteries connected in series would supply how many volts?

• A. 1.5 volts
• B. 2 volts
• C. 3 volts
• D. 4.5 volts

Answer: (C)

When batteries are connected in series, the total voltage output is calculated by summing the individual voltages of each battery. In this case, you have two 1.5-volt alkaline batteries. By connecting them in series, the total voltage would be: 1.5 volts (from the first battery) + 1.5 volts (from the second battery) = 3 volts. This principle is fundamental in understanding how voltage works in series circuits, where the total voltage is the sum of each cell's voltage. This makes it clear why the correct answer is that two 1.5-volt batteries yield a total of 3 volts when connected in series.
