Short circuit protection Circuit is often a desirable feature to add to power amplifiers or power supplies, for both safety concerns and protection of circuitry.

A common example of short-circuit is when positive and negative terminal of a battery or Power Supply are connected together with a low-resistance conductor, like a wire. In this condition, battery or Power supply can set to fire and can even explode. 

To avoid this short circuit condition, Short-circuit Protection Circuit is used. Short-circuit Protection Circuit will divert the flow of current or break the contact between the circuit and the power source. 

So here we are going to study and design circuit to avoid the damage due to short-circuit in it.
