A short circuit is a problem in an electrical circuit where two or more wires that are not supposed to come in contact with each other touch. A short circuit can result in a very high current flowing through the circuit. The high current can destroy components, melt insulation and start a fire. If there is enough voltage, it can also cause an explosion called arc flash. Circuit breakers and fuses are devices that detect short circuits and (usually) shut the power off before any damage can be done.[1]

A "short circuit" also happens when there is a bypass of electrical current. As electricity is "lazy", when there is a bypass without a "load" (e.g. Bulb), it will travel that route of least electrical impedance.
The term "short circuit" is frequently misused to describe any electrical problem.
