What is a consequence of an equipotential mismatch (also known as a short circuit)?

An equipotential mismatch, or short circuit, occurs when there is an unintended low-resistance connection between two points in an electrical circuit, causing a dramatic shift in current flow. This situation leads to an excessive amount of current flowing through the circuit, exceeding the capacity of the wiring and components involved.

Interconnect fusing, which is the result of this excess current, can occur as the materials involved in the circuit heat up due to the increased currents. When the current surpasses the ratings of the circuit components, such as wires or connectors, it may lead to physical melting or fusing of the conductive parts. This can create a permanent bond between the conductors, severely damaging the electrical system and potentially resulting in fire hazards.

In contrast, increased resistance, minimized current flow, and voltage drop do not accurately describe the outcomes of a short circuit. An increase in resistance is usually a preventative measure taken to avoid short circuits, and in the event of a short circuit, the current flow typically increases, not minimizes. Additionally, voltage drop is a common factor in normal circuit operation but is not the primary consequence of a short circuit. Thus, interconnect fusing is the correct consequence of an equipotential mismatch.
