If 12 V and -19 V sources are connected so their total voltage is -7 V, they are ________.
A)series opposing
B)series aiding
C)connected dangerously
D)in parallel

Question

Quizplus · Accepted Answer

When two voltage sources are connected in series opposing, it means their polarities are opposite to each other. In this case, one source has a positive potential of 12 V and the other has a negative potential of -19 V. When these two sources are connected in series opposing, the total voltage across them is the difference between their potentials, i.e., 12 V - 19 V = -7 V. Therefore, the answer is A) series opposing.
