Question

The temperature at which the resistance of conductor becomes 20% more than its resistance at 27°C. (The value of temperature coefficient of resistance of the conductor 2 x 104/K) is​

Answer 1

Answer:

SOLUTION:-

GIVEN BY:-

the resistance at 270oC is  R.

the temperature be T at which resistance become 20% more.

then ,

hence, t = 1324C

■temperature coefficient of resistance of the conductor is 2 x 10^-4 / K
