Consider the following incomplete sentence regarding transistors:
The emitter–…… junction is ___ and the collector– …… junction is ___.
The proper words to fill the dotted empty spaces are, respectively,
The emitter–…… junction is ___ and the collector– …… junction is ___.
The proper words to fill the dotted empty spaces are, respectively,
Options
- A'collector' and 'base'
- B'base' and 'emitter'
- C'base' and 'base'
- D'collector' and 'emitter'
Correct answer
C. 'base' and 'base'
Step-by-step solution
A transistor consists of three regions: emitter, base, and collector.
The two junctions in a bipolar junction transistor are formed between the emitter and the base, and between the collector and the base. These are known as the emitter-base junction and the collector-base junction.
For normal active operation of a transistor, the emitter-base junction is forward biased and the collector-base junction is reverse biased.
Therefore, the proper words to fill the dotted empty spaces are 'base' and 'base', respectively.
