Officially, though, a short circuit refers to a specific condition in which electricity strays outside the established pathway of an electrical circuit. As the name implies, a short circuit is a condition where electrical flow completes its circuit journey via a shorter distance than is present in the established wiring. By nature, electricity seeks to return to ground , and in a properly functioning circuit, this means that the current flows through the established wiring circuit back to the service panel, and onward back through the utility wires.
However, if the connections within the wiring loosen or break, electrical current may "leak. That pathway may very well be through flammable materials or even through a human being, which is why a short circuit presents the danger of fire or lethal shock.
The reason this happens is that these other materials offer a pathway of lesser resistance than is present in the copper wiring of a circuit. For example, in a light switch with faulty wiring or a loose wire connection, if the bare copper hot wire touches the metal electrical box or a metal faceplate on the switch, the current will leap toward whatever path offers the least resistance—which could well be through the finger, hand, and body of whoever is touching the switch.
In general terms, a short circuit is any condition where the establish wiring circuit is interrupted by a flaw in the wiring or wiring connections.

Actually, though, there are two situations that both qualify as short circuits, although they carry different names. The term short circuit is most commonly used by electricians to refer to the situation in which a hot wire carrying live current touches a neutral wire. When this happens, resistance lessens instantly and a large volume of current flows through an unexpected pathway.
When this classic short circuit occurs, sparks sometimes fly, you may hear crackling, and sometimes smoke and flames ensue. As with the classic short circuit, a ground-fault causes resistance to instantly lessen, which allows a large amount of unimpeded current to flow through the unexpected pathway. Here, there is less chance of flame and fire, but a notable chance of shock.
Old or damaged insulation may allow neutral and hot wires to touch, which can cause a short circuit. Nail and screw punctures, as well as age, can cause wire casings or insulation to deteriorate and create short circuits.

Or, if animal pests such as mice, rats, or squirrels gnaw on circuit wiring, the inner wire conductors can be exposed to cause short circuits. Attachments can loosen, sometimes allowing neutral and live wires to touch. Fixing faulty wire connections is tricky and is best handled by those thoroughly familiar with wiring work. When an appliance is plugged into a wall outlet, its wiring effectively becomes an extension of the circuit, and any problems in the appliance wiring become circuit problems.
Old or broken appliances can develop inner short circuits over time. I want to curse the false friend who said I love you forever. I reach up and switch on the bedside lamp. Night springs. I lie listening to the light vibrate in my ears. Falsity and bad love and the deadly pain of alteration are constant topics in. Well, thou halt paid me back my love!
