Question

In an n-p-n transistor in CE configuration, when VC E is increased, then (A) IB increases and IC increases proportionally (B) IB increases and IC remains constant (C) effect on IB is negligible but IC increases (D) Both IB and IC remain nearly constant

IB does not depend on VC E. So, when VC E is increased, IB remains constant. IC increases till saturation.

Q. In an $n - p - n$ transistor in CE configuration, when $V_{CE}$ is increased, then

$I_{B}$ increases and $I_{C}$ increases proportionally

$I_{B}$ increases and $I_{C}$ remains constant

effect on $I_{B}$ is negligible but $I_{C}$ increases

Both $I_{B}$ and $I_{C}$ remain nearly constant

$I_{B}$ does not depend on $V_{CE}$ . So, when $V_{CE}$ is increased, $I_{B}$ remains constant. $I_{C}$ increases till saturation.

Q. In an n−p−n transistor in CE configuration, when VCE​ is increased, then

IB​ increases and IC​ increases proportionally

IB​ increases and IC​ remains constant

effect on IB​ is negligible but IC​ increases

Both IB​ and IC​ remain nearly constant
