In a series circuit containing an open, all the good components will have a voltage
A) increase from their normal value
B) decrease from their normal value to 0V
C) increase from their normal value to the value of the power source
D) that is the same as when the circuit was operating normally

In a series circuit, if there is an open (a break in the circuit), the current flow stops entirely. Since voltage drop across a component is directly proportional to the current flowing through it (V=IR), with no current, the voltage drop across all components decreases to 0V.
