Two identical wires one of Nichrome and other copper are connected in series and a current I is passed through them.State the change observed in the temperature of the 2 wires .Justify your answer .State the law which explains the above observation.Hepl Plzz....

Answer»

We know that RESISTANCE is directly proportional to the temperature.since nichrome is an ALLOY so it has more resistance HENCE , it gets more heated.that is why we use nichrome wire in heater for producing more heat to COOK food.we know that alloy has more resistance than a metal. so nichrome has more heat produced capacity than copper wire.so copper has LESS temperature than nicrome.
