Question
Write an expression for the resistivity of a metallic conductor showing its variation over a limited range of temperatures.
Solution
The resistivity of a metallic conductor is given by
ρT = ρ0 [1 + α (T – T0)]
where,
is the resistivity at temperature T,
ρ0 be the resistivity at temperature T0, and
be the temperature co-efficient.
ρT = ρ0 [1 + α (T – T0)]
where,
is the resistivity at temperature T,
ρ0 be the resistivity at temperature T0, and
be the temperature co-efficient.
