Understanding Short Circuits: Causes, Prevention, and Solutions
A short circuit occurs when there is a low resistance between the two conductors supplying electrical power to a circuit. This leads to excessive current flow and voltage, causing electricity to follow the shortest path and resulting in a short circuit. Short circuits can cause damage, small-scale explosions, and even fires.
