In p-n-p transistor the current IE has two components viz. IEP due to injection of holes from p-region to n-region and IE due to injection of electrons from n-region to p-region. Then
IEp and IEn are almost equal
IEp >> IEn
IEn >> IEp
either (a) or (c)
Correct Answer:
IEp >> IEn
Explanation:
Emitter is
p
-type in
p
-
n
-
p
transistor.
Therefore holes are majority carriers.
