Cause thermal energy

From time to time, however, the relationship between the output and the electric chain becomes problematic. Electric power can cause thermal energy, and this excess heat can lead to the insulation around the wires melt. After exposing the electric wire, it can come into contact with the metal casing of the outlet or even other chain wire. If the connection is installed, then the electrons are jumping through gaps and forming a spark. Since the connection reduces the estimated distance in the chain, this is often called a short circuit.
