Question

the temperature coefficient of resistance of a wire is0.00125 per°c at 300K, Its resistance is 1 ohm. the resistance of the wire will be 2 ohm at​

Answer 1

Answer:

R1= R0 ( 1+aT1) and R2=R0(1+aT2)

thus, R2/R1 = 1+aT2/1+aT1

or T2= 1400K

well... hope it helps u

Answer 2

Answer:

answer is 1400 k
