The load resistance and the base-emitter voltage of a transistor in CE configuration are \(5 \mathrm{k} \Omega\) and \(0.02 \mathrm{~V}\) respectively. If the collector current is \(2 \mathrm{~mA}\), then its voltage gain is
- A \(1000\)
- B \(500\)
- C \(1500\)
- D \(50\)
Answer & Solution
Correct Answer
(B) \(500\)
Step-by-step Solution
Detailed explanation
\(\mathrm{I}_{\mathrm{C}}=2 \times 10^{-3} \mathrm{~A}\) Voltage gain, \(A_v=\frac{V_{C E}}{V_{B E}}=\frac{I_c R_c}{V_{B E}}\) \(=\frac{2 \times 10^{-3} \times 5 \times 10^3}{.02}=500\)
