A transistor converts __________________?
Correct answer: A. c. power into a.c. power
- A. c. power into a.c. power
- B. c. power into d.c. power
- C. high resistance into low resistance
- D. none of the above
Explanation
A transistor uses DC supply power to produce a controlled AC output signal, so it is commonly described as converting DC power into AC power in an amplifier. It does not convert DC power into more DC power.
