Explain working of NMOS transistor.

An NMOS transistor with the voltage across gas source> threshold voltage and with a small voltage between the drain and source applied. The device acts as a resistance whose value is determined by the voltage across the gas source. Specifically, the channel conductance is proportional to the voltage across the gas source – threshold voltage, and thus Id is proportional to (voltage across the gas source – threshold voltage)voltage between the drain and source
