The current gain of a common emitter amplifier is \(69\). If the emitter current is \(7.0\,mA\), collector current is.....\(mA\)
- A \(9.6\)
- B \(6.9\)
- C \(0.69\)
- D \(69\)
Answer & Solution
Correct Answer
(B) \(6.9\)
Step-by-step Solution
Detailed explanation
Given, current gain of \(CE\) amplifier \(\beta=69, \mathrm{I}_{\mathrm{E}}\) \(=7 \mathrm{mA}\) or \(\quad \frac{\mathrm{I}_{\mathrm{C}}}{\mathrm{I}_{\mathrm{B}}}=69\) We know that,…
