The voltage across an open in a series circuit equals
A) zero volts
B) current times resistance
C) the applied voltage
D) the applied voltage minus all other series connected voltage drops

Question

Quizplus · Accepted Answer

In a series circuit, an open circuit means there is a break in the continuity, preventing current from flowing. Since no current flows, there are no voltage drops across any components that might be in series with the open. Therefore, the voltage across the open itself must equal the applied voltage, as there is nowhere else for the voltage to drop.
