When an n-channel MOSFET is turned on,
A) the channel, which is p-type, acts like an n-type semiconductor.
B) the channel, which is n-type, acts like a p-type semiconductor.
C) the drain changes from p-type to n-type.
D) the source changes from n-type to p-type.

Question

Quizplus · Accepted Answer

When an n-channel MOSFET is turned on, the channel, which is inherently n-type, is enhanced to allow current flow. The statement about the channel acting like an n-type semiconductor is correct, as the n-channel MOSFET uses an n-type channel for conducting electrons from source to drain when turned on.
