In a common emitter configuration, a transistor has \(\beta=50\) and input resistance \(1 \mathrm{k} \Omega\). If the peak value of a.c. input is \(0.01 \mathrm{~V}\) then the peak value of collector current is
- A \(0.01 \mu \mathrm{A}\)
- B \(0.25 \mu \mathrm{A}\)
- C \(100 \mu \mathrm{A}\)
- D \(500 \mu \mathrm{A}\)
Answer & Solution
Correct Answer
(D) \(500 \mu \mathrm{A}\)
Step-by-step Solution
Detailed explanation
\[ \text { Hints: } \beta=50 \Rightarrow \beta=\frac{\Delta \mathrm{I}_{\mathrm{C}}}{\Delta \mathrm{I}_{\mathrm{B}}} \Rightarrow \Delta \mathrm{I}_{\mathrm{C}}=\beta \times \Delta \mathrm{I}_{\mathrm{B}} \]…
