Question 357Electricity & Electronics - QMED
70% to passIn the illustration, 1, 2, 3 and 4 are 12 volt batteries. What will be the nominal voltage as read by a voltmeter across the output of the battery bank? Illustration EL-0107
A6 volts
B12 volts
C24 volts
D48 volts
AI Explanation
The correct answer is C) 24 volts. In the illustration, the four 12-volt batteries are connected in series. When batteries are connected in series, their voltages add up. Since there are four 12-volt batteries, the total nominal voltage across the battery bank will be 4 x 12 = 24 volts. The other answer choices are incorrect because: A) 6 volts is the voltage of a single battery, not the total voltage of the battery bank. B) 12 volts is the voltage of a single battery, not the total voltage of the battery bank. D) 48 volts is not the correct voltage, as the four 12-volt batteries are connected in series, not in parallel.
