When the electrical appliances are not connected well or the cables of the electric appliances are worn out,a short circuit may occured.

A short circuit affects the normal operation of electrical appliances connected to the circuit.It has very low resistance that almost all electric current would flow through it.Owing to the heating effect,an excess electric current would produce heat and thus may damage the electric appliances,or even cause a fire,if without a fuse or a circuit breaker.
