Hello,
I am a bit confused about depletion region in NMOSFET transistor. It says here in my book, that when you increase Uds (drain source) above Ugs(gate source) that the current get higher. Ok, makes sense if nothing, from Ohms law. Simultaneously, the depletion region get smaller in length due to that voltage, that is bigger than drain source one(I can grasp with that concept too) but when I put that together, it doesn't make sense...
How can current get higher when the path through it can travel gets smaller(on the other end though).
I attached an relevant image.
