The most important consideration in power amplifier is __________________?
Correct answer: B. Collector efficiency
- A. Biasing the circuit
- B. Collector efficiency
- C. To keep the transformer cool
- D. None of the above
Explanation
Power amplifiers handle large currents and voltages, so efficient conversion of d.c. supply power into useful a.c. output is a primary concern. Collector efficiency measures this conversion, whereas cooling and biasing are supporting design considerations.
