Hello. I didn't count examples about plasma at school. Never yet. I'm trying it study on my own. I do not know what to do with a few examples. I do not know which formula to use. I give here one of them.

Calculate the resistivity of hydrogen plasma at 1 keV.

How can I do it?
How does one define resistivity, or it's reciprocal, conductivity?

"for a conducting medium we define the conductivity, σ, or resistivity, η, by . . . . "

See - (3.139)
