Define "short circuit."

The term "short circuit" refers to an unintentional low-resistance connection between two conductors. In the context of electrical circuits, this means that electricity can take a shortcut through the circuit, bypassing the intended pathway. This occurrence greatly reduces the resistance in the circuit, leading to an excessive current flow that can cause overheating, potential damage to equipment, and even fire hazards.

Understanding this definition is crucial in electrical safety and engineering, as it highlights the need for proper insulation and protection against such unintentional connections. Recognizing the essence of a short circuit helps individuals comprehend the critical nature of circuit design and maintenance, ensuring safe and reliable electrical systems.
