[ Comprehensive information ]

When a positive voltage is applied to the gate terminal, it attracts electrons to the channel, creating an inversion layer and allowing current to flow between the source and drain terminals. N-channel MOSFETs are widely used in a variety of electronic applications due to their high input impedance, fast switching speeds, and low power consumption. They are commonly used as switches, amplifiers, and voltage regulators.
