I would just like a compilation of all equations used to get the information that I am being asked. The textbook goes over the principals as to how these things work, but it seems to be shy or irrelevant as to the questions that are assigned in the homework. It may go over how to find the Vds of a circuit, but it gives you all the information you need. When little to none is provided, it makes it difficult to get the answers.

I need the formulas to calculate in JFET/MOSFET's:

Vs, Vds, Id, Idss, Vgs, Vg, Vd.

Thank you!
