A more general definition of the temperature coefficient of resistivity is given below
α=1/ρ*dρ/dt
where ρ is the resistivity at temperature T.
a) Assuming that α is constant, show that ρ equals the following expression where Po is the resistivity at temperature To.
b)using the series expansion ex = 1 + x for x « 1, show that the resistivity is given approximately by the expression ρ=p0[1 + α(T-TO)] .
