Answer» Functions of fuse: i. Acts as a barrier between the electric circuit and the human body. ii. Prevents device failure due to faulty circuit operation iii. Fuse prevents short- circuits iv. Prevents overload and blackouts v. Prevents damage that is caused due to mismatched loads. Short-circuiting: When the live and neutral wires comes into direct contact, resistance becomes almost zero and current in the circuit abruptly increases. Direct contact of wires is as a result of fault in the appliance or when the insulation of wires is damaged. This is called short circuiting |
