Heeta answered 5 years ago An Anti fuse is a device which fuses when there is a high voltage across it. Just as a fuse opens the circuit in the case of an abnormality, the antifuse closes the circuit in the event of an abnormality.
Raman answered 5 years ago An antifuse is an electrical device that performs the opposite function to a fuse. Whereas a fuse starts with a low resistance and is designed to permanently break an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance and is designed to permanently create an electrically conductive path (typically when the voltage across the antifuse exceeds a certain level). This technology has many applications.
Veer answered 5 years ago The fuse and antifuse are components with completely opposite operating characteristics.
Fuse consists of a conductive filament of low resistance & it is used for protection against over-current. When current higher than rated flows through fuse, due to (I^2)*R loss heat is produced and it leads to melting of fuse element. Thus disconnecting appliance from mains supply.
