how to input the resistance instead of electrical conductivity in the electric current module?

Hi,

I am using the electric current module to model a problem and I have an expression for electrical resistance that I want to use instead of having electrical conductivity. Is there a way that i can input the electrical resistance instead of conductivity?

Thanks,
Rabia

Hi

1[S/m] = 1/(1[ohm*m]) no ?,

so enter your values in the conductance field as 1/my_resisitivy[ohm*m]

Good luck
