What defines a short circuit?

A short circuit is specifically defined as a connection that allows electric current to flow along an unintended path, typically with little or no resistance. This unintended connection can occur when electrical wires touch or when there is a fault in the circuit. As a result, it can lead to an excessive amount of current flowing through the circuit, potentially causing damage to electrical components, overheating, or even fire hazards. This behavior is fundamentally different from other concepts such as resistance or methods of voltage manipulation, highlighting the importance of understanding the unintended paths in electrical systems.
