Question 137Electricity & Electronics - Assistant Engineer

The correct answer is C) 36 volts. When three 12 volt, lead-acid batteries are connected in series, the total voltage is the sum of the individual battery voltages. Since each battery produces 12 volts, connecting them in series results in a total voltage of 12 + 12 + 12 = 36 volts. The other answer choices are incorrect because: A) 12 volts is the voltage of a single battery, not the total voltage when three are connected in series. B) 24 volts would be the correct answer if only two 12 volt batteries were connected in series. D) 48 volts would be the total if four 12 volt batteries were connected in series.
