Q1:

Figure shows characteristics curves for bipolar transistor. These curves are

A output characteristics of n-p-n transistor (common base)

B output characteristics of p-n-p transistor (common base)

C output characteristics of n-p-n transistor (common emitter)

D output characteristics of p-n-p transistor (common emitter)

ANS:B - output characteristics of p-n-p transistor (common base)

Since, here in graph Vcb given is -ve value.

That itself shows that collector is connected by -ve terminal of a battery.
So, for reverse bias collector have to have only P type.that justify PNP.
Correct me if am wrong.
