Hello EE forum !(adsbygoogle = window.adsbygoogle || []).push({});

I would like to talk about conductance and resistance. I understand both terms. And formulas that they derived from.

First newbie question: Each element has conductance and and resistance(admittance)? Probably yes, just checking.

Second question: In process of transforming current generators to voltage generators, conductance term is used. Here is what i mean:

Now I get the analogy of this but, why is conductance used in the first place? I've seen this everywhere, where current generators are written like this, with conductance multiplied by voltage. Especially in the transistor models.

Now why is this written like this? Why not simply with resistance and voltage?

I mean this bothers me probably because I am new to this term, and I find it pointless because the relation between conductance and resistance is simply inverse proportion. Is there any physics behind it? Because current generators work like this? Any thoughts?

Thanks
