distinguishing features between overloading and short circuiting in domestic circuits

 Q. List two distinguishing features between overloading and short circuiting in domestic circuits. (CBSE 2014)

ANS-If too many electrical appliances of high power rating are switched on at the same time, they draw an extremely large current from the circuit causing overloading. 

Due to an extremely large current flowing through the circuit, the copper wire of the household wiring gets heated to a very high temperature and a fire may start. 

Short-circuiting: The touching of naked live wire and neutral wire directly causes short circuiting. In this case, the resistance of the circuit so formed is very small, thus a large amount of current flows through the circuit and heats the wires to a high temperature and a fire may start
