In a junction transistor, the collector current changes by \(6.8 \mathrm{~mA}\), if the emitter current is changed by \(7 \mathrm{~mA}\). For such transistor, the current amplification factor is
- A 30
- B 34
- C 40
- D 45
Answer & Solution
Correct Answer
(B) 34
Step-by-step Solution
Detailed explanation
Given, \(\Delta I_C=6.8 \mathrm{~mA}\) \[ \text { So, } \quad \begin{aligned} \Delta I_E & =7 \mathrm{~mA} \\ \Delta I_B & =0.2 \mathrm{~mA} \end{aligned} \] \(\because\) Current amplification is \(>1\) So, it must be \(\mathrm{CE}\) configuration Amplification factor,…
