If each of the six resistors in a series circuit drops 5 V, the source voltage ________.
A)depends on the current
B)equals 30 V
C)equals 5 V
D)depends on the resistor values

Question

Quizplus · Accepted Answer

The source voltage in a series circuit is equal to the sum of the voltage drops across each resistor. Since each resistor drops 5 V, and there are six resistors, the source voltage is 6 * 5 = 30 V.
