When VG is positive, electrons in the p-type substrate are attracted to the oxide–silicon interface, and form an n-type conduction channel. The electrical model is represented by resistors in series. The transistor is in its ON state.

When VG = 0, the area underneath the oxide layer is still p-type, which forms a “back-to-back” diode with the n region, as shown in the electrical representation. The transistor is in its OFF state.
