T6B04
Which of the following components can consist of three regions of semiconductor material?
- A.Alternator
- B.Transistor (correct answer)
- C.Triode
- D.Pentode
WhyA transistor can consist of three regions of semiconductor material. A bipolar junction transistor is built from three regions of semiconductor material, either NPN or PNP, forming the emitter, base, and collector, answer B. An alternator (A) is a mechanical generator, and triode (C) and pentode (D) are vacuum tube designations, not semiconductor structures.
