Transistors

Question

In case of common-emitter configuration of transistor current gain is more than one, because

Easy

A

$I_{c} < I_{b}$
B

$I_{c} < I_{e}$
C

$I_{c} > I_{b}$
D

$I_{c} > I_{e}$

Solution

$\begin{array}{l} C u r r e n t G a i n : β = \frac{I_{c}}{I_{b}} > 1 \\ ⇒ I_{c} > I_{b} \end{array}$
