Voltage sources connected in parallel must have ____, and care must be taken to match the polarities-positive to positive and negative to negative.
A)the same voltage rating
B)different voltage ratings
C)proportionate voltage ratings
D)equal or smaller voltage ratings

Question

Quizplus · Accepted Answer

Voltage sources connected in parallel must have the same voltage rating to avoid unequal distribution of current, which can lead to damage or failure of the sources. Matching the polarities ensures that the sources are aiding each other rather than working against each other. Choice B, C, and D are not correct because they do not comply with the requirement of having the same voltage rating for the sources connected in parallel.
