What happens to the ions when the drain is turned off? please help :] ❤️

In a long channel MOSFET, the width of the pinch-off region is assumed small relative to the length of the channel. Thus, neither the length nor the voltage across the inversion layer change beyond the pinch-off, resulting in a drain current independent of drain bias. Consequently, the drain current saturates.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
