What is a short circuit and why can it be dangerous?
A short circuit (sometimes abbreviated to short or s/c) in an electrical circuit that allows a current to travel along an unintended path, often where essentially no (or a very low) electrical impedance is encountered. 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.
In short circuit large amount of current will flow in the circuit, which will damage the circuit. Nice Question. But its not shot circuit. It is Short-circuit. Short circuit means that we connect the output terminals of any circuit by means of No Resistance wire(Normally low resistance since we cannot have zero resistance in practical). If there is no resistance then the current will flow through the line will be higher. This increase in current…
A short circuit is when there is a connection between both sides of the supply before the current is sent round the main circuit. It causes large currents to flow and if it causes the fuse to blow or the circuit breaker to trip, that isn't dangerous, just inconvenient. In a poorly installed circuit without protection devices, the large current could cause the wiring and the house to catch fire.
