What would happen to the branch currents in a parallel circuit if one of the branches became short-circuited?
A) Currents would increase slightly
B) Currents would be maximum
C) Currents would decrease to zero
D) Currents would decrease slightly

Question

Quizplus · Accepted Answer

In a parallel circuit, the current in each branch is inversely proportional to the resistance of that branch. If one of the branches becomes short-circuited, its resistance becomes zero, so the current in that branch becomes infinite. This means that all of the current will flow through the short-circuited branch, and the current in the other branches will decrease to zero.
