Q1
A UJT has ___________.
A.
Two pn junctions
B.
One pn junction
AnswerC.
Three pn junctions
D.
None of the above
Answer: Option B
Solution
Answer: Option B
Solution:
A Unijunction Transistor (UJT) has one pn junction.The UJT consists of a single pn junction between its emitter and the base regions.
This single pn junction is used for the UJT's unique characteristics, including its ability to act as a trigger device in various electronic circuits.
Options A and C are incorrect as UJTs do not have two or three pn junctions; the correct number is one.
