Physics Question on Semiconductor electronics: materials, devices and simple circuits
A p-n-p transistor is said to be in active region of operation, when:
A
both emitter junction and collector junction are forward biased
B
both emitter junction and collector junction are reverse biased
C
emitter junction is forward biased and collector junction is reverse biased
D
emitter junction is reverse biased and collector junction is forward biased
Answer
emitter junction is forward biased and collector junction is reverse biased
Explanation
Solution
For amplification of a p-n-p transistor, emitter junction is forward biased and collect junction is reverse biased. In this state, p-n-p transistor is said to be in active region of operation.
