How the metals used in bulb and fuse wire are different? Explain the reason behind using the two different material.
Answers
Answer:
Fuse wire are used to save the home appliances from damagaing by large currents. so they are made up of such materials which have high resistance and low melting point so that they can melt down when unexpected amount of current is passed through.for this work either tin metal or tin-lead alloy will be appropriate.
Explanation:
Answer:
A filament used ina bulb must withstand the high temperature to emit light. The material used to make filament must have high resistance and high melting point. Usually tungsten is used to make a filament.
The fuse wire must get heated and melt whenever excess current passes through it. Hence, it must be made of an alloy with high resistance and low melt-ing point. Usually an alloy of lead and tin is used for this purpose.
