Question
In p-n-p transistor the current I_E has two components viz. I_EP due to injection of holes from p-region to n-region and I_E due to injection of electrons from n-region to p-region. Then
Options
A. I_Ep and I_En are almost equal
B. I_Ep >> I_En
C. I_En >> I_Ep
D. either (a) or (c)

Correct Answer

I_Ep >> I_En

Explanation

Emitter is p-type in p-n-p transistor.

Therefore holes are majority carriers.
