Transformer coupling is used for__________amplification?
Correct answer: A. Power
- A. Power
- B. Voltage
- C. Current
- D. None of the above
Explanation
Transformer coupling is mainly used in power amplifiers because the transformer transfers maximum AC power and provides impedance matching between stages or to the load. RC coupling is preferred for voltage amplification, not power amplification.
