• Short circuit is flow of large amount of current leading to sparking that occurs when the end of circuit are connected by a conductor of very low resistance as compared to that of the circuit.
• It happens due to damage to the insulation of power lines or a fault in electrical appliance due to which current doesn't pass through it
