Question
In a transistor, the base is
Open in App
Solution
The correct option is D an extrinsic semiconductor
In transistor base, emitter and collector are an extrinsic semiconductor but emitter and collector are heavily doped whereas base in very lightly doped, thus base is very thin layered semiconductor compared to emitter and collector.
