# Changes when $V_{be}$ is increased in npn transistor

For the given circuit, a statement has been given in my book, saying

It is obvious that if Vbe is increased by a small amount, both hole current from emitter region and the electron current from the base region will increase. As a consequence both Ib and Ic will increase proportionally

I believe there is a mistake and it should be rather,

electron current from the emitter region

Because BE seems to be forward biased and thus the majority carriers, that is, electrons from Emitter should increase and go into the base and further in collector.

Am I right or wrong?

• Technically, both the book and you are wrong. If the base is indeed fed by a current source, then changing the voltage source will have no effect on the base current (it's being fed by a current source, remember?). – WhatRoughBeast Feb 24 '19 at 20:05
