Q.
A p-n-p transistor is said to be in active region of operation, when:
EAMCETEAMCET 2006Semiconductor Electronics: Materials Devices and Simple Circuits
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.
