Question

The resistance of a conductor is 6 ohm at 50°C and 7 ohm at 100°C . Calculate the mean temperature coefficient of resistance of the material .Find the resistance of the conductor at 0°C

Answer 1

Answer:

5.86 ohm

Explanation:

R= R°[1+X(y-y°)]

[(6/7)-1]/(50-100)= X

X = 0.00286

now,

again using the same equation

R = 6 [1 + 0.00286(0-50)]

R = 5.86 ohm
