For a common emitter transistor, if \(\frac{\mathrm{I}_{\mathrm{C}}}{\mathrm{I}_{\mathrm{E}}}=0.95\), then the current gain is

  1. A \(47.5\)
  2. B \(44\)
  3. C \(19\)
  4. D \(15\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(19\)

Step-by-step Solution

Detailed explanation

\(\alpha = \frac{\mathrm{I}_{\mathrm{C}}}{\mathrm{I}_{\mathrm{E}}} = 0.95\) \(\beta = \frac{\alpha}{1 - \alpha}\)
