Question

Give 2 reasons why nichrome alloy is used for making the heating elements of electrical appliances

Answer 1

As the nichrome is a good conductor of electricity not as good as copper and aluminum thou it conduct .. But it takes its place due to its high melting point so you can just heat it up to a high degree° as it has high resistence .And can carry out your experiment easily ..which otherwise will fail due to some other conductors or coil such as copper and aluminum

Answer 2

in electrical appliances like Electric Iron , electric heater , heating road  the wire of nichrome is used because 

# It has high value of specific resistance 

# its melting point is high . 

# it can easily drawn in wires 

# it is not oxidized easily when heated in air .
