During short circuit, the current increases drastically at the short-circuit spot.
True
In a circuit, when a live wire and a neutral wire come into direct contact (shorted), the current in the circuit increases drastically. The current now flows through a low resistive path consisting of wires rather than domestic electric circuits consisting of resistive components. A fuse is a device which prevents the flow of this large amount of current and thus safeguarding the devices against large current.
