MOSFET Transistors as Switches

I’ve attached two images from my textbook. One describing how MOSFEET’s act like small resistances when in the triode region and open circuits when in the cutoff region, the other a list of equations describing the behavior of an NMOS transistor. I’m having trouble making sense of these two pages. In the triode region, does the drain current depend on the gate-source voltage? These to pages seem to suggest different answers to that question. In the first image, it looks like drain current will increase as the gate-source voltage increases. In the second image, it looks like drain current remains constant as the gate-source voltage increases. drain current seemingly only depends of the drain-source voltage in this case. Any clarification would be helpful, thanks.   Attachments 7085C189-F062-48F7-B6E5-8E08AA8B9CB3.jpeg 69 KB · Views: 85 3C34D527-87BD-4463-80FD-E9637AA0BF81.jpeg 47.7 KB · Views: 73
