A short circuit is a (usually accidental) low-resistance connection between two nodes of an electrical circuit that are meant to be at different voltages. This results in an excessive electric current limited only by the internal impedance of the current source and potentially causes circuit damage, overheating, fire or explosion.
Usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of [voltage-sensing crowbar circuit protectors.
Eg: If you touch the poles of a battery with a wire, you are short circuiting the battery.

a short circuit is nothing but a path which has relatively less resistance.....and current obviously chooses this path to flow. A short circuit is sometimes wanted and sometimes unwanted

We know that current flows through wires.
Every wire has a certain capacity of current that it can allow to flow through it. If the current flowing thorugh a wire is more that that wire's capacity, then there will be a short circuit (the wire will burn).
