Question

The current gain, $\alpha =\frac{\Delta I_C}{\Delta I_E}$ is defined for -

• A. $\text{CE}$ transistor
• B. None of these
• C. $\text{CC}$ transistor
• D. $\text{CB}$ transistor

Answer 1

The correct option is D $\text{CB}$ transistor

The current gain $\alpha =\frac{\Delta I_C}{\Delta I_E}$ is defined for $\text{CB}$ transistor.


Hence, option $\left(A\right)$ is the correct answer.
