  • Prospective short circuit current — The prospective short circuit current (PSCC) is the highest electric current which can exist in a particular electrical system under short circuit conditions. It is determined by the voltage and impedance of the supply system. It is of the order… …   Wikipedia

  • Short circuit — A short circuit (sometimes abbreviated to short or s/c) allows a current along a different path from the one intended. The electrical opposite of a short circuit is an open circuit , which is an infinite resistance between two nodes. It is common …   Wikipedia

  • short circuit — [1] An electrical problem in which the hot or positive wire touches ground. It takes a short path to ground instead of going through the prescribed component. Usually a short circuit (also called a short) will burn out a fuse or a component. [2]… …   Dictionary of automotive terms
