If you measure a lower than normal total current in a parallel circuit, ________.
A)all of the resistors are opened
B)a resistor opened
C)the power supply is off
D)a resistor shorted

Quizplus · Accepted Answer

In a parallel circuit, the total current is equal to the sum of the currents flowing through each branch. If one resistor is open, it will interrupt the flow of current in that branch, reducing the total current in the circuit. Therefore, if you measure a lower than normal total current in a parallel circuit, it is likely that one of the resistors opened.
