A)8 V, 4 V
B)4 V, 8 V
C)4 V, 4 V
D)8 V, 8 V

Quizplus · Accepted Answer

In a series circuit, the voltage is divided among the resistors in proportion to their resistances. The total resistance is 15 kΩ. The voltage across the 10 kΩ resistor is (10/15) * 12V = 8V, and across the 5 kΩ resistor is (5/15) * 12V = 4V.
