State a difference between the wire used in the element of an electric heater and in a fuse wire.

(N/A) The wire used in the element of an electric heater is made of an alloy (like Nichrome) which has a very high resistance and a high melting point,allowing it to produce heat without melting. In contrast,a fuse wire is made of a material with a low melting point and appropriate resistance,designed to melt and break the circuit when the current exceeds a safe limit.
