Question

For alloys the value of temperature coefficient of resistance is very high true or false

Answer 1

Heya user

here is ur answer


yes it is true For alloys that the value of temperature coefficient of resistance is very high

Answer 2

absolutely false.

Some alloys have temperature coefficient nearly zero, some even have a negative one. There isn’t any general rule.

Some do have a very high positive coefficient, they are used for heating coils because that makes the heating self-regulating.
