SUMMARY
In circuits with resistors in parallel, if one branch contains a resistor (rA) and the other branch is a direct wire (short circuit), the total resistance of the circuit is determined by the short circuit. Specifically, rA does not contribute to the total resistance when it is effectively short-circuited, resulting in an equivalent resistance of zero for that branch. This conclusion is based on the fundamental principles of parallel resistor calculations.
