Expert Answer:

A short circuit in an electrical circuit is one that allows a current to travel along a different path from the one originally intended. This can be achieved by connecting a low resistance wire between the two terminals and in parallel with the original resistance through which initial current flow is expected. Now the current will flow this new low resistance than the original one, resulting in short circuit.

While in electrical circuit overloading an element such as resistor which rated for the maximum current it can carry safely, actually carries a higher current than rated. The resistor heats up and blows.
