In the unit of work done, $Nm$, $N $ stands for the force applied and $m$ stands for the length of displacement, by taking their product we get work done or $Nm$.
But in the case of electrical resistivity, $ohm-meter$, I know that $ohm$ stands for resistance of wire which is not defined for a given resistivity, and $metre$ stands for something i don't understand.
1.What is the meaning of ohm-meter?
2.Also tell me what is electrical resistivity? (not asking its derivation in this question)
