The output transformer used in a power amplifier is a _____________ transformer?
Correct answer: C. Step-down
- A. 1:1 ratio
- B. Step-up
- C. Step-down
- D. None of the above
Explanation
A power amplifier's output transformer is generally step-down to reduce the high transistor-side voltage and provide the larger current required by a low-resistance speaker load.
