If four 1.5-volt batteries are wired in series, what is the resulting voltage?

If four 1.5-volt batteries are wired in series, what is the resulting voltage?

• A. 3 volts
• B. 4.5 volts
• C. 6 volts
• D. 9 volts

Answer: (C)

When batteries are connected in series, the total voltage is the sum of the individual voltages of each battery. In this case, each battery provides 1.5 volts. Therefore, when four 1.5-volt batteries are connected in series, you add their voltages together:

1.5 volts + 1.5 volts + 1.5 volts + 1.5 volts = 6 volts.

Thus, the resulting voltage from four 1.5-volt batteries wired in series is 6 volts. This principle of adding up the voltages holds true for any number of batteries in series, making it a fundamental concept in electrical circuits.
