- A \(0.29 \mathrm{~mA}\)
- B \(0.35 \mathrm{~mA}\)
- C \(0.39 \mathrm{~mA}\)
- D \(10 \mathrm{~mA}\)
Answer & Solution
Correct Answer
(A) \(0.29 \mathrm{~mA}\)
Step-by-step Solution
Detailed explanation
Given, current gain, \(\alpha=0.96\) Emitter current, \(I_E=7.2 \mathrm{~mA}=7.2 \times 10^{-3} \mathrm{~A}\) We know that,…
