Short Circuit

Short circuits usually happen when a hot wire touches any of the other two wires in your fuse box. This causes extra current to flow through the circuit, which causes the circuit breaker to trip or the fuse to blow. However, this is not the only reason for short circuits to occur. There are many potential problems in electric circuits, such as faulty wiring, broken insulation, circuit overload, as well as defective plugs, switches, cords, and receptacles. One can take place in both direct and alternating current circuits.

Warning: Short circuits can be dangerous, as they can produce very high temperatures due to the high current flow through the circuit, which may cause the wire to explode and catch fire. This same principle is applied deliberately in the world of arc welding, which uses electricity to generate huge amounts of heat.

Safeguards: The use of safety fuses and circuit breakers, which disconnect the electricity in reaction to an excessive current, can often reduce the damage that a short circuit cause and are also helpful in isolating the exact location of the short circuit. If you suspect a short circuit has occurred, you can test this by turning on a switch or plugging in a particular electrical appliance. If doing so causes the lights in the rest of the house to go out, then it's a short.
