short circuit Scientific  
/ shôrt /
  1. An electrical path in a circuit that causes most of the current to flow around or away from some other path in the circuit. Accidental short circuits, especially between the high and low voltages of a power supply, can cause very strong current to flow, possibly damaging or overheating the circuit.


short circuit Cultural  
  1. An electrical circuit in which a path of very low resistance has been opened, usually accidentally. When the resistance drops, the electric current (see also current) in the circuit becomes very high and can cause damage to the circuit and start fires.
