Electric and thermal conductivities
☉ Thermal conductivity
It represents the heat transferred per surface value and per second when a specific thermal gradient is applied.
Its unit is Watt per meter per Kelvin: W.M-1.K-1
☉ Electric conductivity
It is the inverse of the electric resistivity.
The conductivity is the capacity to let the electric current flow. It is the inverse of resistivity.
It is expressed in Siemens : G = 1/R
Note
☉ Thermal or electric conductivity: two closely related notions. (see above chart)
If we change the unit: electric conductivity in 10 (7) S/m (Siemens/m) / thermal conductivity in W/m.K
A very strong link exists … but!
-
Big difference of total energy transferred.
-
Reflexivity of the thermal conductivity: cold/hot ≠ electric energy.
