Question

The current gain for a transistor used in common-emitter configuration is 98. If the load resistance be 1M W and the internal resistance be 600W. What is the voltage gain?

• A. 90
• B. 95
• C. 100
• D. None

Answer 1

Answer: (D)

None

Answer 2

A = $\frac{\beta R_{L}}{R_{L} + R_{i}}$= $\frac{98 \times 10^{6}}{10^{6} + 600}$= 98
