Detailed Solution
Download Solution PDFThe correct answer is option 3.
Bipolar junction transistor
- The Bipolar Junction Transistor (BJT) is a three-terminal device i.e. Base, Emitter, and Collector.
- There are two main types of bipolar junction transistors the NPN and the PNP transistor.
- The emitter is a heavily doped region of the BJT transistor, providing the majority of carriers into the base region.
- The base region is a thin, lightly doped region sandwiched between the emitter and collector.
- The majority of carriers from the emitter pass through the base region and its flow can be externally controlled.
