Hi

I'm confused about the basic stuffs

Please see the following steps and check if it's correct

1) a wire has an inductance
2) longer wire has higher inductance
3) an electrically long wire is a transmission line
4) therefore, an inductor = kind of a transmission line

A lossless tranmission line small signal model has a series inductance and parallel capacitances, but I'm confused whether the opposite way is also correct or not.

Thanks.

Inductor is Lumped component and Transmission line is a Distributed component.
Any transmission line with length less then ~1/10 of a wavelength is considered as Lumped, this means that depending on the working frequency same wire can be just an inductor or a TL.
Go to the basics and read about distributed networks.
