Hello to everyone. I am a little confused regarding what stands for the designation of [Ohm/m]. Before I used to [Ohm*m] for designation of resistivity (it calls sometimes resistance per unit length). For example I have a wire (copper). The resistivity could be found from the table (17.2 [nOhm*m]). What means Ohm/m for the same wire and how I can unite it at one (by equation)? I suppose that it should be done in this way: [Ohm/m]=R/L (R - usual resistance, L - length of the wire)={ro*L/S}/L = ro/S, where ro is actually resistivity [Ohm*m]; S - cross-section of wire. - Is that correct?
And, by the way, how can I call the unit [Ohm/m]? Is that also called resistance per unit length??
I Will be thankful for the explanation.
