An open in one branch of a parallel circuit results in:
A)decreased or reduced current flow.
B)decreased power consumption.
C)increased circuit resistance.
D)all of these.

Question

Quizplus · Accepted Answer

An open in one branch of a parallel circuit leads to decreased current flow through that branch (effectively zero), which in turn reduces the overall power consumption of the circuit. Additionally, the overall resistance of the circuit increases because the total resistance in a parallel circuit is inversely related to the sum of the reciprocals of each branch's resistance. Removing a branch increases the total resistance.
