<Tr> <Td> </Td> <Td> Look up short circuit in Wiktionary, the free dictionary . </Td> </Tr> <P> A short circuit (sometimes abbreviated to short or s / c) is an electrical circuit that allows a current to travel along an unintended path with no or a very low electrical impedance . This results in an excessive amount of current flowing into the circuit . The electrical opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes . It is common to misuse "short circuit" to describe any electrical malfunction, regardless of the actual problem . </P> <P> A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages . This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion . Although usually the result of a fault, there are cases where short circuits are caused intentionally, for example, for the purpose of voltage - sensing crowbar circuit protectors . </P> <P> In circuit analysis, a short circuit is defined as a connection between two nodes that forces them to be at the same voltage . In an' ideal' short circuit, this means there is no resistance and thus no voltage drop across the connection . In real circuits, the result is a connection with almost no resistance . In such a case, the current is limited only by the resistance of the rest of the circuit . </P>
