Question

The power gain in common base amplifiers is

• A. high
• B. low
• C. moderate
• D. very high

Answer 1

The correct option is C moderate

$Answer:-$ B

This transistor configuration provides a low input impedance while offering a high output impedance. Although the voltage is high, the current gain is low and the overall power gain is also low when compared to the other transistor configurations available. The other salient feature of this configuration is that the input and output are in phase.
