How does a short circuit happen and what are its potential consequences?

A short circuit happens when an electrical current takes an unintended path due to a direct connection between two points in a circuit with low resistance. This can lead to overheating, sparks, fires, and damage to electrical components. The potential consequences of a short circuit include electrical fires, damage to equipment, and even electrical shocks. It is important to address short circuits promptly to prevent accidents and ensure safety.
