Electric fuse wire is made of alloys because alloys -
|
|
Are economical
|
|
|
Have low melting point
|
|
|
Have high melting point
|
|
|
Do not get heated easily
|
Explanation:
Detailed explanation-1: -Due to their high resistance and low melting point, tin and lead are combined to form the fuse wire. The composition of the tin and lead alloy, which melts at 183 ° C, is tin and lead.
Detailed explanation-2: -The material used for a fuse wire must have a low melting point so that it melts as soon as excessive current passes through it and thus it can prevent the appliance from damage.
Detailed explanation-3: -Solution: Fuse wire is made of alloy of lead and tin having low melting point of 200°C.
